| Abstract: | The chemical non-equilibrium flows over a teflon ablative wall are calculated numerically by solving NS equations with pure-air and teflon-air chemical reaction system. The overall teflon-air chemical system used consists of 19 species and 28 reactions. The effect of wall injection of teflon ablating material on electron number density are discussed. |
