Abstract
In this long term project the behaviour of a twin scroll turbocharger in an engine environment with pulsating boundary conditions is investigated. A complete three dimensional turbocharger fluid model is built including exhaust manifold, turbine and compressor housing as well as the complete runners. The turbine and the compressor side is coupled by a momentum equilibrium (and) the instantaneous rotational speed of the turbocharger is calculated for each timestep. This model is capable of analyzing both, the transient pulse efficiency, which is generated by the working cycle and the operating behavior, especially the overflow losses in a twinscroll turbine caused by pressure pulses.
