dc.description.abstractWith an intention of discovering the best RANS model for modeling impinging flows, linear epsilon - based models(`Chien's Low Reynolds' and -f') and non-linear( and !- based) EARSM formulations were implemented on OpenFOAM-2.2.x and validated against two dimensional, developed channel flow geometries. The project arose from the need to capture flow arising from a flame impingement on the walls of an (internal combustion) engine cylinder. The objective desired from this project is to achieve directives regarding `optimal' turbulence models, defined as those which sufficiently reproduce the flow dynamics, and are applicable over a wide variety of meshes, while not being too costly on the computational front. A rating scheme for judging the quality of turbulence models, based on the aforementioned three characteristics, is discussed as part of the conclusions from this thesis project.
