STAR-CCM+

In-cylinder simulation in STAR-CCM+

An updated road map of in-cylinder migration from STAR-CD® into STAR-CCM+® will be presented. Material will include the current status of migration activities, upcoming critical events, and a demonstration of the latest version of the upcoming add-on for setting up in-cylinder simulations in STAR-CCM+.

Piston bowl optimization using STAR-CD and HEEDS

A multi-objective optimization is carried out to drive bowl shape and injector optimization of a CI engine for automotive application.

Both full-load and part-load operations are simulatenously accounted for in the optimization loop in order to cover a reasonably broad range of engine operations.

Impact of wall heat transfer on engine behavior

The effect of thermal wall functions is discussed in terms of engine thermal balance, thermal state characterization and impact on engine performance. In particular, the newly implemented GruMo-UniMORE wall function is applied to improve the prediction of knock limit in SI engines and combustion behavior in CI engines.
