Summary:

LDV is used to measure steady flow in a two port loop scavenged model two-stroke engine cylinder. The model cylinder, machined from acrylic for maximum optical access, is geometrically identical to that used in a previous dynamic study of transfer port efflux vectors. The measured flow field is compared with a CFD prediction which employs experimentally measured velocity, mass flow rate, and turbulence intensity as the inlet boundary condition at the transfer portrait The finite volume prediction, using the PHOENICS general purpose code recreates the global flow pattern well, but shows some local discrepancies in flow direction and magnitude. Levels of turbulent kinetic energy were poorly recreated using a k- model of turbulence, especially around impingement of the incoming jets where local errors of up to 60% were seen
