Catalytic recombination of nitrogen and oxygen on high-temperature reusable surface insulation

摘要: The energy transfer catalytic recombination coefficient for nitrogen and oxygen on the surface coating of high-temperature reusable insulation (HRSI) is inferred from stagnation point heat flux measurements in a dissociated arc jet flow. resulting coefficients are correlated with an Arrhenius model convenience, these expressions may be used to account effects predictions HRSI thermal protection system Space Shuttle Orbiter during reentry flight. Analysis pressure total balance enthalpy indicates that heater reservoir conditions not chemical equilibrium. This contrary what usually assumed analysis need suitable diagnostics analyses, especially when dealing reaction phenomena such as effects.
