Effect of Transport Coefficient Modeling on Hypersonic Non-Equilibrium Flow Simulations

Effect of Transport Coefficient Modeling on Hypersonic Non-Equilibrium Flow Simulations by Xiaowen Wang_ Numerical Simulations Abstract Many important scientific and engineering applications, such as strong shock and turbulence interactions and hypersonic boundary-layer stability and transition, involve strong shocks and high temperature effects. These processes are strongly nonlinear and proven to be very complex to understand with existing tools. The most widely used shock capturing methods may incur numerical oscillations near the shock and may not be accurate enough for Numerical Simulations of hypersonic boundary-layer stability and transition problems. To solve such problems, a unique approach of using high-order shock-fitting method is adopted, where the shock is treated by shock-fitting method as a sharp boundary. However, there are no reported studies on the effects of transport coefficient modeling, chemical reaction rate and equilibrium const...
