The 1st report clarified the superiority of the atomic oxygen injected from a plasma torch with the diffusive mode operation for initiating supersonic combustion. In this paper the features of combustion enhancement by various combinations of plasma mole flux and heat flux are investigated. The effectiveness of each combination is evaluated by H2O production efficiency. A molecular dynamical numerical simulation technique with the reactional molecular collision model is applied for the analysis of multi-species reaction system. The results of parametric study show that the effect of atomic oxygen plasma is attributed to the mole flux, whilst the strong dependence on the heat flux is observed for the atomic hydrogen plasma.
