Validating Simcenter STAR-CCM+ In-cylinder Solution

Capturing global in-cylinder quantities and details of the turbulent flow characteristics at a high level of accuracy is a precondition to any sophisticated in-cylinder simulation like mixture preparation and combustion prediction. Together with Siemens, the research department of Daimler AG conducted a study on transient Reynolds-averaged Navier-Stokes (RANS) simulation of gas exchange in an optically accessible gasoline direct injection engine to assess the capabilities of the Simcenter™ STAR-CCM+™ In-cylinder solution.
