A method for solving the unsteady heat transfer and ablation problem for a body
Abstract
A method for calculating the unsteady heating and ablation of a solid is proposed which is a modification of the straight line method wherein a cubic spline is used to approximate the temperature field in its principal change direction. The method is tested on a one-dimensional model by comparing it with an exact solution. It is shown that by introducing few bands in the main temperature change direction, satisfactory results can be obtained for heat transfer problems typical for hypersonic flows.
