概要	This paper presents discussions on predicting turbulence and heat transfer in complicated flow fields by recent low Reynolds-number (LRN) second moment closures. The flow fields discussed are two types of square sectioned U-bend duct flows with mild and strong curvature. The strain fields are complex and thus so are the heat transfer characteristics. A version of the Two-Component-Limit (TCL) second moment closure and Shima's "wall-reflection free" model are presently focused on. They are LRN models totally free from geometrical parameters. For turbulent heat flux, the higher order version of the generalized gradient diffusion hypothesis is applied along with the TCL model. The results are compared with those of the nonlinear cubic k-ε-A2 eddy viscosity model.
