A supersonic flowfield with transverse sonic injection of hydrogen is calculated by using the two-dimensional Reynolds time-averaged full Navier-Stokes equations and q-omega turbulence model developed by Coakley. A Yee's type second-order explicit symmetric TVD scheme is applied for spatial discretizations of convective terms of the equations. Wall pressure distribution of numerical results is compared with experimental data, and it is shown that the turbulence model is useful. In addition, the interactions between hydrogen injection and incident shock or expansion wave are simulated by the same procedure. The numerical results show that hydrogen distribution in the flowfield becomes smaller by shock wave and larger by expansion wave slightly. When total temperature rises after an incident shock wave, which means a modeling of chemical reaction in flow, an interaction flowfield with injection changes drastically. This suggests the importance of the similar study in chemically reacting flow.
