Abstract

In the present work, the use of the Jameson-Schmidt-Turkel (JST) dissipation scheme is successfully extended to compute hypersonic flows over an airfoil. It is shown that this scheme is not only capable of computing flows at speeds all the way up to Mach 50, but also the rate of convergence and the final results are as good as those obtained using the Swanson-Turkel modification of the JST scheme and better than the Yoon-Kwak flux limited dissipation specially designed to compute high-speed flows. The scheme is seen to be so robust that it does not require a well-prepared starting solution to compute flows with either strong shocks or with high incidence, or both.
