Abstract

The turbocharger is particularly important for today’s gasoline engines. Considering the compressor the special flow conditions close to surge are the focus of attention. In addition to the challenges related to mechanics and engine performance the acoustic issues have great importance in this operating range. The turbocharger acoustics are investigated by numerical simulations and the improvements achieved are validated experimentally. The acoustic flow simulation using CFD is proven worth in different engine applications.
