Simulation of the Scavenging Process in Two-Stroke Engines

It is widely known that the scavenging process plays a very important role in the performance and efficiency of two-stroke engines. Briefly, scavenging is the process by which the fresh charge displaces the burnt gas from the cylinder. Due to the difficulties associated with the measurement techniques, CFD (Computational Fluid Dynamics) is a very helpful tool to analyze the flow pattern inside the cylinder. CFD simulations can provide more detailed information than experimental studies. For this reason, this chapter focuses on a numerical analysis to simulate the fluid flow and heat transfer inside the cylinder at the scavenging process.
