三次元非等方性乱流場における熱流動解析

抄録

A numerical analysis has been made on a three-dimensional distorting duct using a Reynolds stress equation model and transport equation model for heat flux. It is important to examine the validity of an anisotropic turbulent model for the flow with complex configuration because we do not know the worth of the anisotropic turbulent model until we apply it. We compared the calculated results with the published experimental data and made clarified that the present method was able to predict the mean flow field, but it is necessary to modify the convective and diffusion terms of a Reynolds stress equation.
