Numerical Simulation of Scavenging Process of Large 2-Stroke Marine Diesel Engine

Abstract

Abstract-Computational Fluid Dynamics (CFD) is of great importance for R&D of Large 2-Stroke Marine Diesel Engine. The CFD software ANSYS FLUENT was adopted to calculate the scavenging process of a large 2-stroke marine diesel engine MAN B&W S60MC-C6 and the obtained pressure trace was compared with the shop test data. The swirl flow field was analyzed on the achieved satisfactory in-cylinder pressure agreement. This provides a good reference for the application of CFD to the optimization of large 2-stroke marine diesel engine scavenge process.
