Investigation of the application of RANS turbulence models to the calculation of nonisothermal low-Prandtl-number flows
Tóm tắt
The RANS turbulence models intended for modeling turbulent low-Prandtl-number flows are described. With reference to the example of sodium liquid-metal heat-transportmedium the specialized models presented are compared with the standard RANS models having the highest rating. The adequacy of modeling heat transfer using the specialized models is studied with reference to the example of a heated backward-facing step for which both thermal and dynamic parameters are evaluated.
