Abstract
The steady blunt body problem is solved using a time-dependent technique. The steady solution is reached asymptotically. The computation is performed in the shock layer only, assuming that the shock wave is a discontinuity surface, dependent on time. A technique similar to the one used by Richtmyer, Lax, and Wendroff is applied to the points between shock and body, whereas the shock and body points are analyzed with a three-dimensional method of characteristics. In this way a coarse mesh can be used, and little time is needed on the computer to achieve accurate results. Detailed results for two-dimensional (symmetric and asymmetric) blunt bodies and for axisymmetric ones are given and compared with experimental data. A brief critical comparison of the present technique with other methods also is given.
