Abstract

A CFD method is developed to calculate heat transfer rate for a sphere with wall injection in hypersonic flow. An attention is paid to explore the enhanced heat transfer rate by wall injection. The concept of injection-induced turbulence effect is employed in which the injection flow is assumed to be inherently turbulent. A detailed comparison of the calculated heat transfer distributions with existing experimental data is carried out. Although the quantitative agreement is not yet accomplished for the entire wall surface, the enhanced heat transfer rate at the stagnation point is well reproduced, and the higher heating rate in the downstream region is indicated in the calculated results.
