ABLATION OF A CYLINDRICAL CAVITY IN AEDIUM,
Abstract
An approximate solution is presented for the ablation of a cylindrical cavity in an infinite medium. The spatial variation of temperature in the unablated solid is assumed in the form of an exponential, and a heat balance integral tech nique is used to satisfy the heat conduction equation on the average. The solution is in the form of a second order, nonlinear ordinary dif ferential equation in the position of the ablat ing surface. The results of a numerical integra tion of the nonlinear equation are compared with the total ablation measured at the stagnation point of a Plexiglas hemisphere tested in a hypersonic environment. A discussion of the approximate method, and the comparison with the test on the Plexiglas hemisphere appears in the body of the paper. (Author)
