The effects of various radical species, supplied from a plasma torch ignitor upon initiating hydrogen-air chemical reaction in a two-dimensional supersonic shear flow have been investigated by a new numerical approach based on the molecular gas dynamics. Direct Simulation Monte Carlo (DSMC) method has been employed to derive the microscopic reaction phenomena from the Boltzmann equation with a reactive inelastic molecular collision model (IE Model). The plasma species and injection mode into air stream have been varied. The result shows that fuel hydrogen initial combustion can be significantly enhanced by plasma injection of atomic oxygen supplying in diffusive mode.
