Numerical analysis of small radial compressor aeroacoustics through data-driven modal decomposition

Abstract: Small radial compressors are found in many engineering applications, such as automotive turbochargers, fuel cell boosters, micro gas turbines, etc. In many of these applications, acoustics is becoming a concern for both manufacturers and integrators. Moreover, inlet and outlet duct geometries significantly influence both performance and noise emission of the compressor. The objective of this seminar is to showcase how data-driven modal decomposition techniques can be applied to numerical simulations of small radial compressors to improve the understanding of their acoustic behaviour and the impact of geometry changes. 

Bio: Jorge García Tíscar holds the position of Associate Professor at the CMT - Clean Mobility & Thermofluids Institute of the Polytechnic University of Valencia (UPV), Spain. His main research topic is the experimental and numerical study of rotating machinery aeroacoustics, including small radial compressors and UAV propellers. Other research interests include combustion noise in reciprocating engines and gas turbines, and aerothermal studies of turbofan heat exchangers.

He also serves as the Vice-dean for Industry Chairs at the Aerospace Engineering and Industrial Design School at UPV, as Vice-chair for the ASME Technical Committee on Microturbines, Turbochargers & Small Turbomachinery, as Chair of the EUCASS Technical Committee on CFD & Multi-Physics Simulation in Aerospace, and as representative of UPV in the PEGASUS network.
