Formatted abstract
The parameters that are involved in heat transfer behind a step in high-enthalpy laminar hypersonic flow are investigated. The nondimensional wall heat transfer coefficient such as the Stanton Number depends on a group of dimensionless parameters characteristic of the flow. The flow enthalpies (h o) ranged from 1.5 MJ/kg to 26 MJ/kg, thus covering both undissociated and mildly to moderately dissociated freestreams. The gas phase, Damkohler number, ranged from 0 (undissociated flow) to 0.133. The dissociated freestream may be frozen as a result of nozzle expansion in shock tunnel and expansion tube flows. The part of the freestream total enthalpy may be stored as chemical potential enthalpy, which would be result in reduced heat transfer.
