Computational Fluid Dynamics for Atmospheric Entry

Abstract

These notes are arranged in the following manner. In the introduction section, we use several examples to illustrate some of the issues that must be addressed when we model hypersonic flows. This leads to a discussion of what types of computational fluid dynamics methods are suitable for these flows. Then the conservation equations for a mixture of chemically reacting and weakly ionized gases is developed. We discuss the thermochemistry models and the relevant boundary conditions for these flows. Then in the third section, computational fluid dynamics methods for these flows are discussed. We analyze the conservation equations, and discuss an upwind method. Then, the integration of the source terms is discussed. In the fourth section we discuss several advanced topics in the modeling of hypersonic flows.
