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.
