Inviscid, nonadiabatic flow fields over blunt, sonic corner bodies for outer planet entry conditions by a method of integral relations
Abstract
An investigation has been made into the ability of a method of integral relations to calculate inviscid zero degree angle of attack, radiative heating distributions over blunt, sonic corner bodies for some representative outer planet entry conditions is investigated. Comparisons have been made with a more detailed numerical method, a time asymptotic technique, using the same equilibrium chemistry and radiation transport subroutines. An effort to produce a second order approximation (twostrip) method of integral relations code to aid in this investigation is also described and a modified twostrip routine is presented. Results indicate that the onestrip method of integral relations cannot be used to obtain accurate estimates of the radiative heating distribution because of its inability to resolve thermal gradients near the wall. The twostrip method can sometimes be used to improve these estimates; however, the twostrip method has only a small range of conditions over which it will yield significant improvement over the onestrip method.
