Abstract: In this paper an insight into the problem of the |sliding-valve| effect is discussed for general industrial applications. The |curved-pipe| effect is also considered for applications in two-stroke engines. The background to the treatment of variable openings for two-stroke engines is reviewed. A novel method for a moving mesh is presented in the simulation of a changing geometry with variable openings using a multi-dimensional CFD code. The results of applying this model to direct-fuel-injection two-stroke engines are presented.

Keywords: 3D transient flow; CFD moving mesh; curved pipe effect; sliding valve effect; variable openings; computational fluid dynamics; simulation; two-stroke engines.
