Although one of the most important subjects in present engineering CFD is development of practical turbulence models, turbulence models having been proposed are too complicated for actual applications. Though computations using turbulence models have some problems, there is a possibility that computations using turbulence models are in the main stream of engineering CFD fields in future. The research group for the application of turbulence models consists of young researchers who actually work in the field of engineering CFD. The aims of the group are: (1) establishment and conduction of a systematic method which improves computation accuracy of the turbulent flows in various application problems; and (2) establishment of new applications of the existing turbulence models. The principal aim of the group is not for the construction of a turbulence model, so pure users of models can take part in the group without difficulty. Now there are 24 members in the group, and the members are increasing. A seminar is held once every two months, and the members compute a flow problem given by the host using their own code and model, and have discussions. The results are published on the Web site of the group. As a subject of the group, the two-dimensional wall jet experiment by Karlsson et al. (1993) is given. In this report, one example of the calculated results using low Reynolds number k-epsilon model (Myong-Kasagi model) is presented. The computation results are compared to the result of experiment on the average velocity, self-similarity, and so on.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
