Abstract

The present work concerns development and application of turbulence models for forced convective heat transfer in ducts. The numerical approach is based on the finite volume technique and a non-staggered arrangement is employed. The SIMPLEC-algorithm is used for handling the pressure-velocity coupling. Cyclic boundary conditions are imposed in the main flow direction. The standard k-* model with wall functions is used as a reference. The non-linear k-* model of Speziale is applied to calculate the turbulent shear stresses. The turbulent heat fluxes are calculated by the simple eddy diffusivity concept, the GGDH method and the WET method. The overall comparison between the methods is presented in terms of the friction factor and average Nusselt number. In particular the secondary flow field is investigated.
