ANALYSIS OF VORTEX HEAT TRANSFER IN A TRANSVERSE FLOW PAST A TRENCH ON A PLANE USING MULTIBLOCK COMPUTATION TECHNOLOGIES AND DIFFERENT SEMI-EMPIRICAL MODELS OF TURBULENCE

摘要

Vortex dynamics and heat transfer in a viscous incompressible fluid flow past shallow and deep trenches on a plane wall are studied methodically within the framework of the multiblock approach to solution of steady-state Reynolds equations closed by the Menter and Spalart-Allmaras turbulence models and the energy equation.
