Compressibility effect on heat transfer intensified by horseshoe vortex structures in turbulent flow past a blunt-body and plate junction

Results of numerical simulation of turbulent heat and mass transfer in the 3D problem of flow past a blunt-body and plate junction are presented. Comparison with the known experimental data is given; solution grid sensitivity is discussed. Numerical solutions obtained for incompressible fluid flows...

Summary:Results of numerical simulation of turbulent heat and mass transfer in the 3D problem of flow past a blunt-body and plate junction are presented. Comparison with the known experimental data is given; solution grid sensitivity is discussed. Numerical solutions obtained for incompressible fluid flows with different Prandtl numbers, and for the compressible gas flow with the Mach number ranging from 0.01 to 0.5 are analyzed. The effect of compressibility on heat transfer intensification in the region occupied by horseshoe-shaped vortex structures is investigated.
