Engine Performance

The analysis of acoustics phenomena that are induced by flow separation (e.g. side mirror of a car)
Performance simulation of internal combustion engines (ICE) is an essential module for our competence fields of Thermal Management and Acoustics.

For Thermal Management applications we retrieve important boundary conditions from ICE performance simulation such as exhaust temperatures and heat transfer coefficients in combustion chambers, turbochargers and exhaust systems. Other important input parameters can be derived from compressor performance analysis for the layout and design of e.g. charge air cooler.

For Acoustic analyses of exhaust and air induction systems it is essential to accurately predict opening and closing of the valves in conjunction with the correct cylinder pressure and gas temperature. The pulses generated by the valve dynamics produce the pressure waves which are responsible for noise levels and quality at the exhaust tailpipe or air intake snorkel.

For performance simulation we use the software package GT-POWER, the industry standard used by all major engine manufacturers. For thermal management or acoustics analyses we make either use of generic models or we receive appropriate models directly from our customers. Those simulation models will typically be refined to generate utmost accurate boundary conditions that fit our simulation methodologies.
