The Stagnation Line Solution of the Equilibrium Flow with Radiation and Mass Injection

The chemical equilibrium viscous shock-layer equations at stagnation line are solved numerically in this paper. The effects of radiation and mass injection are considered. The detailed line and continuum radiation models are included. The flowfield is devided into two zone as the surface mass injected, one is from the surface to v= 0 in which contains the injected species, and the other is from v= 0 to the shock in which there are no injected species.The minimum free energy method is used in determining the species concentrations. The effects of different injection rates, nose radius and free stream velocities on the convective and radiative heat transfer are discussed. The results are compared with those from references and they agree quite well with each other.
