Abstract

A rapid compression machine (RCM) has been built in order to investigate the effects of a one-dimensional compression upon swirling flow in an environment typical for Diesel engines. In compliance with the experimental program, the numerical investigations consist of both a statistically stationary and a transient spin down behaviour of the induced swirling flow. Additionally, the instationary decaying flow is compressed by a ID piston movement, which results in an extremely complex nature of the flow field under investigation. An integral part of such a flow is the swirl, which is used to enhance turbulent mixing and to stabilize the combustion process in IC engines. In the RCM, the swirl is generated by the rotation of the cylinder wall, providing a well defined initial state of the flow prior to the piston movement, i.e. compression.
