Despite the increasing interest in multidimensional combustion engine
simulation from researchers and industry, the field of application has
been restricted to stationary operating points for turbocharged engines.
Andreas Kächele presents a 3D-CFD approach to extend the simulation into
the transient regime, enabling the detailed analysis of phenomena during
changes in engine operating point. The approach is validated by means of
a virtual hot gas test bench and experiments on a two-cylinder engine.
