Dissertations, Theses, and Masters Projects

In recent years, different approaches for modeling Reynolds stresses have been pursued by various authors. Two different closure schemes, representing two schools of thought, have been selected. The first closure scheme is the k-&\varepsilon& model. The second closure scheme is the level two model. Each group has claimed that the proposed models are an improvement and an advancement over previous models employing the mixing length hypothesis as a closure scheme. Neither group however, has made thorough comparisons between the newly proposed schemes and the most commonly used approach the mixing length hypothesis. The main objective of this paper is to …
