High-resolution direct numerical and large-eddy simulation would be ideal but both are usually too costly despite developments in high performance computing. Lower-order modeling approaches are therefore of general interest. A crucial but standing problem for accurate predictive modeling is the estimation of missing noise from the modeled scales. In this paper we address this problem by presenting a novel lower-order framework that couples the one-dimensional turbulence model to the Ffowcs-Williams and Hawkings approach for prediction of the far-field noise of a subsonic turbulent round jet.}, language = {en} } @misc{SharmaGeyerGiesler, author = {Sharma, Sparsh and Geyer, Thomas and Giesler, Jens}, title = {Effect of geometric parameters on the noise generated by rod-airfoil configuration}, series = {Applied Acoustics}, volume = {177}, journal = {Applied Acoustics}, issn = {0003-682X}, doi = {10.1016/j.apacoust.2021.107908}, pages = {13}, language = {en} } @misc{SharmaGeyer, author = {Sharma, Sparsh and Geyer, Thomas}, title = {Numerical Investigation of Aerodynamic Noise Generation by Porous-Coated Staggered Cylinders}, series = {28th AIAA/CEAS Aeroacoustics Conference 2019, Southampton, UK, 14 - 18 June 2022}, journal = {28th AIAA/CEAS Aeroacoustics Conference 2019, Southampton, UK, 14 - 18 June 2022}, doi = {10.2514/6.2022-2890}, language = {en} } @misc{SharmaKleinSchmidt, author = {Sharma, Sparsh and Klein, Marten and Schmidt, Heiko}, title = {Modelling turbulent jets at high-Reynolds number using one-dimensional turbulence}, series = {AIAA AVIATION 2021 FORUM}, journal = {AIAA AVIATION 2021 FORUM}, publisher = {American Institute of Aeronautics and Astronautics, Inc.}, isbn = {978-1-62410-610-1}, doi = {10.2514/6.2021-2104}, language = {en} } @misc{SharmaAytonKleinetal., author = {Sharma, Sparsh and Ayton, Lorna and Klein, Marten and Schmidt, Heiko}, title = {Estimation of ODT-resolved acoustic sources in high Reynolds number turbulent jets}, series = {Book of Abstracts of the 93rd Annual Meeting of the International Association of Applied Mathematics and Mechanics}, journal = {Book of Abstracts of the 93rd Annual Meeting of the International Association of Applied Mathematics and Mechanics}, publisher = {GAMM e.V.}, address = {Dresden}, pages = {414 -- 415}, language = {en} } @misc{GeyerVelpulaSharma, author = {Geyer, Thomas and Velpula, Rishi and Sharma, Sparsh}, title = {Experimental Investigation of Tonal Noise Radiation from Trapezoidal Cylinders in Cross-Flow}, series = {AIAA AVIATION 2023 Forum, 12-16 June 2023, San Diego, CA and Online}, journal = {AIAA AVIATION 2023 Forum, 12-16 June 2023, San Diego, CA and Online}, doi = {10.2514/6.2023-3496}, language = {en} } @inproceedings{SharmaGeyerSarradj, author = {Sharma, Sparsh and Geyer, Thomas and Sarradj, Ennes}, title = {Time Domain Boundary Element Method for the Leading-Edge Noise subjected to Linear Vorticity}, series = {INTER-NOISE 2018, the 47th International Congress and Exposition on Noise Control Engineering, Chicago, Illinois, USA}, booktitle = {INTER-NOISE 2018, the 47th International Congress and Exposition on Noise Control Engineering, Chicago, Illinois, USA}, pages = {10}, language = {en} }
