Spectral Solution of the Viscous Blunt Body Problem. 2: Multidomain Approximation

摘要

We present steady solutions of high speed viscous flows over blunt bodies using amultidomain Chebyshev spectral collocation method. The region with the shock layer is divided into subdomains so that internal layers can be well-resolved. In the interiors of the subdomains, the solution is approximated by Chebyshev collocation. At interfaces between subdomains, the advective terms are upwinded and the viscous terms are treated by a penalty method. The method is applied to
