A shock-shock hot interaction problem is studied numerically. A high-order Godunov-type scheme coupled with solution-adaptive unstructured grids has been employed to compute a hypersonic thermochemically nonequilibrium viscous flow; the impinging shock generated by a wedge interacts with the bow shock around a 2-D circular cylinder. The dynamic grid adaptation to solution and the high-resolution methods contribute to a considerable improvement in both accuracy and efficiency. High-temperature real gas effects have been evaluated by a thermal and chemical non-equilibrium model. Type IV interaction of Edney near the transition between Type III and Type IV is obtained. The shock interaction structure is clearly captured with high resolution.
