Full TextAbstract
Presently there is a little information that relates to heat shield systems. Also this information is not certain in so many cases. The main reason is that accurate calculations for measuring the sacrificing rate of various materials have not been obtained yet. Additionally, the real scale test has two disadvantages: high cost and low flexibility, and for each case we must perform a new test. So having a reliable numerical program that calculates the surface recession rate and interior temperature history is necessary. In this study numerical solution of unsteady governing equations for non-charring material ablation are presented in order to anticipate the recession rate and the heat response of non-charring heat shields.
