The calculations are performed for a Reynolds number of 5.E4, a Prandtl number of 3.0 and a constant temperature boundary condition is applied on all four sides of the duct. The solution exploits symmetry by performing the calculation over one quadrant of the duct cross section only. The flow Reynolds number is based on the hydraulic diameter of the duct. The RSTM calculations are made with one of two variants, namely: the IPM pressure-strain model (IRSMHM=0) or the QIM pressure-strain model (IRSMHM=2). A transport model (IRSMSM=2) is employed for closure of the turbulent heat-flux components. ENDDIS ************************************************************ Group 1.
