{The settling velocities of helminth eggs of three types, namely Ascaris suum (ASC), Trichuris suis (TRI), and Oesophagostomum spp. (OES), in clean tap water are computationally determined by means of computational fluid dynamics, using the general-purpose CFD software ANSYS Fluent 18.0. The previous measurements of other authors are taken as the basis for the problem formulation and validation, whereby the latter is performed by comparing the predicted sink velocities with those measured in an Owen tube. To enable a computational treatment, the measured shapes of the eggs are parametrized by idealizing them in terms of elementary geometric forms. As the egg shapes show a variation within each class, "mean" shapes are considered. The sink velocities are obtained through the computationally obtained drag coefficients. The latter are defined by means of steady-state calculations. Predicted sink velocities are compared with the measured ones. It is observed that the calculated values show a better agreement with the measurements, for ASC and TRI, compared to the theoretical sink values delivered by the Stokes theory. However, the observed agreement is still found not to be very satisfactory, indicating the role of further parameters, such as the uncertainties in the characterization of egg shapes or flocculation effects even in clean tap water.}, language = {en} } @article{BenimIqbalJoosetal.2016, author = {Benim, Ali Cemal and Iqbal, Sohail and Joos, Franz and Wiedermann, Alexander}, title = {Numerical Analysis of Turbulent Combustion in a Model Swirl Gas Turbine Combustor}, series = {Journal of Combustion}, volume = {2016}, journal = {Journal of Combustion}, publisher = {Hindawi}, issn = {2090-1968}, doi = {10.1155/2016/2572035}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-28044}, pages = {1 -- 12}, year = {2016}, language = {en} } @article{PfeiffelmannBenimJoos2018, author = {Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {Numerical analysis of liquid jet impingement cooling of a thermoelectric generator}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001032}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27988}, year = {2018}, language = {en} } @article{IqbalPfeiffelmannBenimetal.2018, author = {Iqbal, Sohail and Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {Numerical analysis of lifted hydrogen flame}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001014}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27950}, year = {2018}, language = {en} } @article{BenimEppleKrohmer2005, author = {Benim, Ali Cemal and Epple, B. and Krohmer, B.}, title = {Modelling of pulverised coal combustion by a Eulerian-Eulerian two-phase flow formulation}, series = {Progress in Computational Fluid Dynamics, An International Journal}, volume = {5}, journal = {Progress in Computational Fluid Dynamics, An International Journal}, number = {6}, publisher = {inderscience}, doi = {10.1504/pcfd.2005.007067}, pages = {345}, year = {2005}, language = {en} } @article{BiswasMandalMannaetal.2022, author = {Biswas, Nirmalendu and Mandal, Dipak Kumar and Manna, Nirmal K. and Benim, Ali Cemal}, title = {Magneto-hydrothermal triple-convection in a W-shaped porous cavity containing oxytactic bacteria}, series = {scientific reports}, volume = {12}, journal = {scientific reports}, publisher = {Springer Nature}, issn = {2045-2322}, doi = {10.1038/s41598-022-18401-7}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40041}, year = {2022}, abstract = {Bioconvective heat and mass transport phenomena have recently been the subject of interest in diverse fields of applications pertaining to the motion of fluids and their thermophysical properties. The transport processes in a system involving triple convective phenomena, irregular geometry, and boundary conditions constitute a complex phenomenon. This work aims to explore the mixed thermo-bioconvection of magnetically susceptible fluid containing copper nanoparticles and oxytactic bacteria in a novel W-shaped porous cavity. The buoyant convention is generated due to the isothermal heating at the wavy bottom wall, whereas the mixed convection is induced due to the shearing motion of the top-cooled sliding wall. Furthermore, the bioconvection is induced due to the manifestation of oxytactic bacteria or organisms. The inclined sidewalls are insulated. The geometry is packed with water based Cu nanoparticle mixed porous structure, which is subjected to a magnetizing field acted horizontally. The complex transport equations are transformed into nondimensional forms, which are then computed using the finite volume-based developed code. The coupled triple-convective flow physics are explored for a wide range of involved controlling parameters, which could provide helpful insight to the system designer for its proper operation. The shape of geometry can be considered one of the important parameters to control the heat and mass transport phenomena. In general, the influence of amplitude (δ) is more compared to the waviness number (m) of the undulations. The magnitude of heat (Nu) and mass (Sh) transfer rate for the W-shaped cavity is high compared to conventional square and trapezoidal-shaped cavities. The output of the analysis could be very helpful for the designer for modeling devices operating on nanotechnology-based bioconvection, microbial fuel cells, and others.}, language = {en} } @article{BenimSyedKhawarJ1998, author = {Benim, Ali Cemal and Syed, Khawar, J.,}, title = {Laminar flamelet modelling of turbulent premixed combustion}, series = {Applied Mathematical Modelling}, volume = {22}, journal = {Applied Mathematical Modelling}, number = {1-2}, publisher = {Elsevier}, doi = {10.1016/s0307-904x(98)00012-2}, pages = {113 -- 136}, year = {1998}, language = {en} } @article{MabroukBenimNajietal.2023, author = {Mabrouk, Riheb and Benim, Ali Cemal and Naji, Hassane and Dhahri, Hacen}, title = {Investigation of Pulsed Flow Effects on the Phase Change Within an Open-Cell Metal Foam Using Thermal Lattice Boltzmann Method}, series = {Transport in Porous Media}, volume = {147}, journal = {Transport in Porous Media}, number = {2}, publisher = {Springer Nature}, issn = {0169-3913}, doi = {10.1007/s11242-023-01903-x}, pages = {225 -- 257}, year = {2023}, language = {en} } @article{AslanTaymazBenim2015, author = {Aslan, Erman and Taymaz, Imdat and Benim, Ali Cemal}, title = {Investigation of LBM curved boundary treatments for unsteady flows}, series = {European Journal of Mechanics - B/Fluids}, volume = {51}, journal = {European Journal of Mechanics - B/Fluids}, publisher = {Elsevier}, doi = {10.1016/j.euromechflu.2015.01.004}, pages = {68 -- 74}, year = {2015}, language = {en} } @article{BhattacharyyaChattopadhyayGuinetal.2019, author = {Bhattacharyya, Suvanjan and Chattopadhyay, Himadri and Guin, Anindya and Benim, Ali Cemal}, title = {Investigation of Inclined Turbulators for Heat Transfer Enhancement in a Solar Air Heater}, series = {Heat Transfer Engineering}, volume = {40}, journal = {Heat Transfer Engineering}, number = {17/18}, publisher = {Taylor \& Francis}, doi = {10.1080/01457632.2018.1474593}, pages = {1451 -- 1460}, year = {2019}, language = {en} } @article{Benim2022, author = {Benim, Ali Cemal}, title = {Introducing the "Mathematical Modelling and Numerical Simulation of Combustion and Fire" Section of the Journal Fire}, series = {fire}, volume = {5}, journal = {fire}, number = {6}, publisher = {MDPI}, issn = {2571-6255}, doi = {10.3390/fire5060178}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40257}, year = {2022}, language = {en} } @article{SenthurAnandRameshKumaretal.2022, author = {Senthur, N.S. and Anand, C and Ramesh Kumar, M and Elumalai, P.V. and Shajahan, Mohamed Iqbal and Benim, Ali Cemal and Nasr, Emad Abouel and Hussein, H.M.A. and Parthasarathy, M.}, title = {Influence of cobalt chromium nanoparticles in homogeneous charge compression ignition engine operated with citronella oil}, series = {Energy Science \& Engineering}, volume = {10}, journal = {Energy Science \& Engineering}, number = {4}, publisher = {Wiley}, issn = {2050-0505}, doi = {10.1002/ese3.1088}, pages = {1251 -- 1263}, year = {2022}, language = {en} } @article{MandalBiswasMannaetal.2202, author = {Mandal, Dipak Kumar and Biswas, Nirmalendu and Manna, Nirmal K and Benim, Ali Cemal}, title = {Impact of chimney divergence and sloped absorber on energy efficacy of a solar chimney power plant (SCPP)}, series = {Ain Shams Engineering Journal}, journal = {Ain Shams Engineering Journal}, publisher = {Elsevier}, issn = {2090-4495}, doi = {10.1016/j.asej.2023.102390}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-42410}, year = {2202}, abstract = {A numerical study is carried out meticulously to scrutinize the impact of different shapes of chimneys like circular (outer dia, dc), convergent (outer dia, 0.5dc), divergent (outer dia, 1.5dc), sudden contraction (outer dia, 0.5dc), and sudden expansion (outer dia, 1.5dc) on the performance of an SCPP.

Individual components used to install the extracorporeal circulation have an impact on the level of activation, most predominantly membrane oxygenators and hardshell venous reservoirs as used in extracorporeal systems. The blood flows in two different hardshell reservoirs are computationally investigated. A special emphasis is placed on the prediction of an onset of transition and turbulence generation. Reynolds-averaged numerical simulations (RANS) based on a transitional turbulence model, as well as large eddy simulations (LES) are applied to achieve an accurate prediction. In the LES analysis, the non-Newtonian behavior of the blood is considered via the Carreau model. Blood damage potential is quantified applying the Modified Index of Hemolysis (MIH) based on the predicted flow fields. The results indicate that the flows in both reservoirs remain predominantly laminar. For one of the reservoirs, considerable turbulence generation is observed near the exit site, caused by the specific design for the connection with the drainage tube. This difference causes the MIH of this reservoir to be nearly twice as large as compared to the alternative design. However, a substantial improvement of these performance criteria can be expected by a local geometry modification.}, language = {en} } @article{BhattacharyyaChattopadhyayBenim2017, author = {Bhattacharyya, Suvanjan and Chattopadhyay, Himadri and Benim, Ali Cemal}, title = {Computational investigation of heat transfer enhancement by alternating inclined ribs in tubular heat exchanger}, series = {Progress in Computational Fluid Dynamics}, volume = {17}, journal = {Progress in Computational Fluid Dynamics}, number = {6}, publisher = {Inderscience Enterprises Limited}, issn = {1468-4349}, doi = {10.1504/PCFD.2017.088818}, pages = {390 -- 396}, year = {2017}, language = {en} } @article{BenimPfeiffelmannOcłońetal.2019, author = {Benim, Ali Cemal and Pfeiffelmann, Bj{\"o}rn and Ocłoń, Paweł and Taler, Jan}, title = {Computational investigation of a lifted hydrogen flame with LES and FGM}, series = {Energy}, volume = {173}, journal = {Energy}, publisher = {Elsevier}, issn = {0360-5442}, doi = {10.1016/j.energy.2019.02.133}, pages = {1172 -- 1181}, year = {2019}, language = {en} } @article{AliFarooqShahzadetal.2022, author = {Ali, R. and Farooq, A. and Shahzad, A. and Benim, Ali Cemal and Iqbal, A. and Razzaq, M.}, title = {Computational approach on three-dimensional flow of couple-stress fluid with convective boundary conditions}, series = {Physica A: Statistical Mechanics and its Applications}, volume = {553}, journal = {Physica A: Statistical Mechanics and its Applications}, publisher = {Elsevier}, issn = {0378-4371}, doi = {10.1016/j.physa.2019.124056}, year = {2022}, language = {en} } @article{BenimDiederichGueletal.2018, author = {Benim, Ali Cemal and Diederich, Michael and G{\"u}l, Fethi and Oclon, Pawel and Taler, Jan}, title = {Computational and experimental investigation of the aerodynamics and aeroacoustics of a small wind turbine with quasi-3D optimization}, series = {Energy Conversion and Management}, volume = {177}, journal = {Energy Conversion and Management}, publisher = {Elsevier}, doi = {10.1016/j.enconman.2018.09.042}, pages = {143 -- 149}, year = {2018}, language = {en} } @article{PfeiffelmannDiederichGueletal.2020, author = {Pfeiffelmann, Bj{\"o}rn and Diederich, Michael and G{\"u}l, Fethi and Benim, Ali Cemal and Heese, Markus and Hamberger, Andreas}, title = {Computational and Experimental Investigation of an Industrial Biomass Furnace}, series = {Chemical Engineering \& Technology}, volume = {43}, journal = {Chemical Engineering \& Technology}, number = {8}, publisher = {Wiley}, issn = {1521-4125}, doi = {10.1002/ceat.201900637}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27747}, pages = {1538 -- 1546}, year = {2020}, language = {en} } @article{DenizCanalBokeAydinetal.2021, author = {Deniz Canal, Cansu and Boke, Yakup Erhan and Aydin, Ozer and Benim, Ali Cemal}, title = {COMPUTATIONAL ANALYSIS OF PULVERIZED COAL CO-FIRING WITH BIOMASS IN 150MWe UNIT OF TUNCBILEK THERMAL POWER PLANT}, series = {Isi Bilimi ve Teknigi Dergisi - Journal of Thermal Science and Technology}, volume = {41}, journal = {Isi Bilimi ve Teknigi Dergisi - Journal of Thermal Science and Technology}, number = {1}, issn = {1300-3615}, doi = {10.47480/isibted.979314}, pages = {37 -- 50}, year = {2021}, language = {en} } @article{BenimEscudierNahavandietal.2011, author = {Benim, Ali Cemal and Escudier, M.

A Eulerian-Lagrangian formulation is used to describe the two-phase flow. Turbulence is modelled within a RANS (Reynolds averaged numerical simulation) framework. Four turbulence viscosity- (TV) based models, namely the standard k-ε model, realizable k-ε model, renormalization group theory k-ε model, and the shear stress transport k-ω model are used. In addition, a Reynolds stress transport model (RSM) is employed. The models are assessed by comparing the predicted velocity fields with the measurements of other authors. In terms of overall average values, the agreement of the predictions to the measurements is observed to be within the range 20-40\%. A better performance of the RSM compared to the TV models is observed, with a nearly twice as better overall agreement to the experiments, particularly for the swirl velocity. In the second part of the investigation, the resolution of the discrete particle phase in modelling the turbulent particle dispersion (TPD) and particle size distribution (SD) is investigated. Using the discrete random walk model for the TPD, it is shown that even five random walks are sufficient for an accuracy that is quite high, with a less than 1\% mean deviation from the solution obtained by thirty random walks. The approximation of the measured SD is determined by a continuous Rosin-Rammler distribution function, and inaccuracies that can occur in its subsequent discretization are demonstrated and discussed. An investigation on the resolution of the SD by discrete particle size classes (SC) indicates that 12 SC are required for an accuracy with a less than 1\% mean deviation from the solution with 18 SC. Although these numbers may not necessarily be claimed to be sufficiently universal, they may serve as guidance, at least for SD with similar characteristics}, language = {en} } @article{MabroukNajiBenimetal.2022, author = {Mabrouk, Riheb and Naji, Hassane and Benim, Ali Cemal and Dhahri, Hacen}, title = {A State of the Art Review on Sensible and Latent Heat Thermal Energy Storage Processes in Porous Media: Mesoscopic Simulation}, series = {Applied Sciences}, volume = {12}, journal = {Applied Sciences}, number = {14}, publisher = {MDPI}, doi = {10.3390/app12146995}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40343}, year = {2022}, language = {en} } @article{BenimCicekEker2018, author = {Benim, Ali Cemal and Cicek, Aydin and Eker, Arif Mert}, title = {A numerical analysis of the thermohydraulics of an EGS project in Turkey}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824005001}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27910}, year = {2018}, language = {en} }
