Abstract
In this paper we discuss how thermo-chemical nonequilibrium models must be chosen to suit specific hypersonic flows. Current models can be very complicated, involving a large chemical kinetics model and many internal energy modes. Also, realistic hypersonic flows have a very large range of length scales, making them difficult to simulate with computational methods. Therefore, it is important to use thermo-chemical models that are appropriate; the models should have sufficient complexity to capture the relevant properties of the flow, with a minimum of computational cost. Thus, there is no single thermo-chemical model that is appropriate for all re-entry flows, and more complicated models may not be useful because they make the problem computationally intractable.
