Many important scientific and engineering applications, such as strong shock and turbulence interactions and hypersonic boundary-layer stability and transition, involve strong shocks. 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. Furthermore, effects of internal energy excitations, translation-vibration energy relaxation, ionizations, and chemical reactions among different species need to be considered, because gas temperature increases dramatically after strong shocks. To solve such problems, a unique approach of using high-order shock-fitting method is adopted, where the main shock is treated by shock-fitting method as a sharp boundary. The code is validated by comparisons with experimental datasets and numerical simulation results obtained from open literature.
