To increase the efficiency and economic viability of TEGs, research is performed on the materials on one hand and on the system connection on the other. In the latter case, the net output power of the cooling system plays a key role. At first glance, passive cooling seems preferable to active cooling because it does not affect the net electrical output power. However, as shown in the present review, the active cooling is to be preferred for net output power. The situation is similar in air and water-cooling. Even though air-cooling is easier to set up, the water-cooling should be preferred to achieve higher net output power. It is shown that microchannel cooling has similar hydraulic performance to conventional cooling and inserts increase the net output power of TEG. As the review reveals that active water-cooling should be the method of choice to achieve high net output power, it also shows that a careful optimization is necessary to exploit the potential.}, language = {en} } @article{PfeiffelmannOezmanBenimetal.2019, author = {Pfeiffelmann, Bj{\"o}rn and {\"O}zman, Cansu and Benim, Ali Cemal and Joos, Franz}, title = {Variable temperature effects on TEG performance}, series = {E3S Web of Conferences}, volume = {128}, journal = {E3S Web of Conferences}, publisher = {edp sciences}, issn = {2267-1242}, doi = {10.1051/e3sconf/201912807004}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27893}, year = {2019}, language = {en} } @article{BenimGuelAssmannetal.2016, author = {Benim, Ali Cemal and G{\"u}l, Fethi and Assmann, Alexander and Akhyari, Payam and Lichtenberg, Artur and Joos, Franz}, title = {Validation of loss-coefficient-based outlet boundary conditions for simulating aortic flow}, series = {Journal of Mechanics in Medicine and Biology}, volume = {16}, journal = {Journal of Mechanics in Medicine and Biology}, number = {2}, publisher = {World Scientific}, doi = {10.1142/s0219519416500111}, year = {2016}, language = {en} } @article{BenimPfeiffelmann2019, author = {Benim, Ali Cemal and Pfeiffelmann, Bj{\"o}rn}, title = {Validation of Combustion Models for Lifted Hydrogen Flame}, series = {E3S Web of Conferences}, volume = {128}, journal = {E3S Web of Conferences}, publisher = {edp sciences}, issn = {2267-1242}, doi = {10.1051/e3sconf/201912801014}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27815}, year = {2019}, language = {en} } @article{SaeedrashedBenim2019, author = {Saeedrashed, Younis Saida and Benim, Ali Cemal}, title = {Validation Methods of Geometric 3D-CityGML Data for Urban Wind Simulations}, series = {E3S Web of Conferences}, volume = {128}, journal = {E3S Web of Conferences}, publisher = {edp sciences}, issn = {2267-1242}, doi = {10.1051/e3sconf/201912810006}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27906}, year = {2019}, language = {en} } @article{BenimNahavandiSyed2005, author = {Benim, Ali Cemal and Nahavandi, A. and Syed, Khawar J.}, title = {URANS and LES analysis of turbulent swirling flows}, series = {Progress in Computational Fluid Dynamics, An International Journal}, volume = {5}, journal = {Progress in Computational Fluid Dynamics, An International Journal}, number = {8}, publisher = {inderscience}, doi = {10.1504/pcfd.2005.007680}, year = {2005}, language = {en} } @article{ChattopadhyayBenim2011, author = {Chattopadhyay, Himadri and Benim, Ali Cemal}, title = {Turbulent Heat Transfer Over a Moving Surface Due to Impinging Slot Jets}, series = {Journal of Heat Transfer}, volume = {133}, journal = {Journal of Heat Transfer}, number = {10}, publisher = {ASME}, doi = {10.1115/1.4004075}, year = {2011}, language = {en} } @article{BhattacharyyaGobindaDasChattopadhyayetal.2019, author = {Bhattacharyya, Suvanjan and Gobinda Das, Sampad and Chattopadhyay, Himadri and Benim, Ali Cemal and Moghimi, M.

Both the sidewalls of the enclosure are cooled and undulated with varying undulation numbers. The lower wall is partially undulated following a semi-circular-shaped object and is heated isothermally. The horizontal walls are insulated. The cavity is occupied with Cu-Al2O3/water-based hybrid nanofluid and porous substances under the impact of the evenly applied horizontal magnetic field. This work significantly contributes to the existing research rendering an exhaustive understanding of the hydrothermal flow-physics as well as irreversibility production of a hybrid nanofluid in the cavity having surface undulation. The Galerkin weighted finite element method is utilized to solve the mathematical model. The hydrothermal performance of the thermal system is considerably influenced by various pertinent factors such as Darcy-Rayleigh number, Darcy number, Hartmann number, and number of undulations. The wall undulations have a critical role in altering the hydrothermal performance. Heatlines are used to analyse heat transport dynamics from the protruded hot surface to the heat sink. The protruded heater wall induces the formation of a hot upward plume in the nearest fluid layers. The flow divides into two parts forming a pair of circulations due to symmetrical cooling at the sidewalls. The flow behaviours are significantly dampened by increasing the Hartmann number. The associated total entropy generation is also demonstrated. This study contributes to the existing domain knowledge and provides insights for designing and optimizing similar thermal systems.}, subject = {W{\"a}rme{\"u}bertragung}, language = {en} } @article{BhattacharyyaBenimPathaketal.2020, author = {Bhattacharyya, Suvanjan and Benim, Ali Cemal and Pathak, Manabendra and Chamoli, Sunil and Gupta, Ashutosh}, title = {Thermohydraulic characteristics of inline and staggered angular cut baffle inserts in the turbulent flow regime}, series = {Journal of Thermal Analysis and Calorimetry}, volume = {140}, journal = {Journal of Thermal Analysis and Calorimetry}, number = {3}, publisher = {Springer Nature}, issn = {1388-6150}, doi = {10.1007/s10973-019-09094-8}, pages = {1519 -- 1536}, year = {2020}, language = {en} } @article{SuhBenim1989, author = {Suh, S.-H. and Benim, Ali Cemal}, title = {The primitive variables formulation of the Navier-Stokes equations using the finite analytic method}, series = {Applied Mathematical Modelling}, volume = {13}, journal = {Applied Mathematical Modelling}, number = {9}, publisher = {Elsevier}, issn = {0307-904X}, doi = {10.1016/0307-904X(89)90066-8}, pages = {550 -- 554}, year = {1989}, subject = {Navier-Stokes-Gleichung}, language = {en} } @article{FarooqAliBenim2018, author = {Farooq, Asma and Ali, Ramzan and Benim, Ali Cemal}, title = {Soret and Dufour effects on three dimensional Oldroyd-B fluid}, series = {Physica A: Statistical Mechanics and its Applications}, volume = {503}, journal = {Physica A: Statistical Mechanics and its Applications}, publisher = {Elsevier}, issn = {0378-4371}, doi = {10.1016/j.physa.2018.02.204}, pages = {345 -- 354}, year = {2018}, language = {en} } @article{MandalBoseBiswasetal.2024, author = {Mandal, Dipak Kumar and Bose, Sharmistha and Biswas, Nirmalendu and Manna, Nirmal K. and Cuce, Erdem and Benim, Ali Cemal}, title = {Solar Chimney Power Plants for Sustainable Air Quality Management Integrating Photocatalysis and Particulate Filtration: A Comprehensive Review}, series = {Sustainability}, volume = {16}, journal = {Sustainability}, number = {6}, publisher = {MDPI}, issn = {2071-1050}, doi = {10.3390/su16062334}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-45814}, pages = {31}, year = {2024}, abstract = {Urban air pollution has become a pressing challenge in recent times, demanding innovative solutions.

Recent advancements, such as the integration of photocatalytic reactors (PCRs) for the elimination of greenhouse gases (GHGs), emphasizing the importance of addressing non-CO2 GHGs like CH4 and N2O are analyzed. The novelty of this review is that it not only focuses on the shifting and removal of particulate matter but also on the removal of greenhouse gases. Numerous case studies, ranging from filter-equipped SCPPs to Solar-Assisted Large-Scale Cleaning Systems (SALSCSs), are reviewed, providing a comprehensive understanding of their design, performance, and potential benefits.

{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} } @inproceedings{YalcınkayaDurmazTepeetal.2024, author = {Yal{\c{c}}{\i}nkaya, Orhan and Durmaz, Ufuk and Tepe, Ahmet {\"U}mit and Benim, Ali Cemal and Uysal, {\"U}nal}, title = {Numerical Analysis of Roughened Target Surface for Enhancing Jet Impingement Cooling}, series = {Advances in Computational Heat and Mass Transfer: Proceedings of the 14th International Conference on Computational Heat and Mass Transfer (ICCHMT 2023), 4-8 September, 2023, D{\"u}sseldorf, Germany}, volume = {1}, booktitle = {Advances in Computational Heat and Mass Transfer: Proceedings of the 14th International Conference on Computational Heat and Mass Transfer (ICCHMT 2023), 4-8 September, 2023, D{\"u}sseldorf, Germany}, publisher = {Springer Nature}, address = {Cham}, isbn = {9783031672408}, issn = {2195-4356}, doi = {10.1007/978-3-031-67241-5_64}, pages = {713 -- 720}, year = {2024}, subject = {Numerische Str{\"o}mungssimulation}, 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{SulaimanSaberHasanetal.2026, author = {Sulaiman, Mohammed A. and Saber, Hindren Ali and Hasan, Hasan F. and Benim, Ali Cemal}, title = {Latent heat cold storage integrated direct evaporative cooler: A neoteric practical design for energy and water saving potential with thermal comfort improvement}, series = {Journal of Energy Storage}, volume = {143}, journal = {Journal of Energy Storage}, publisher = {Elsevier}, issn = {2352-152X}, doi = {10.1016/j.est.2025.119612}, pages = {20}, year = {2026}, subject = {Latentw{\"a}rmespeicher}, 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{BenimSyed1998, 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}, issn = {0307-904X}, doi = {10.1016/S0307-904X(98)00012-2}, pages = {113 -- 136}, year = {1998}, subject = {Verbrennung}, language = {en} } @inproceedings{BenimCicek2022, author = {Benim, Ali Cemal and {\c{C}}i{\c{c}}ek, Ayd{\i}n}, title = {Investigation of the Thermohydraulics of an EGS Project in Turkey: Comparative Assessment of Water and CO2 as Heat Transfer Fluid}, series = {Proceedings of CONV-22: Int.
