Heat Transfer Behind a Step in High-Enthalpy Laminar Hypersonic Flow

摘要

It is shown that within the frame work of hypersonic small disturbance theory, it is possible to correlate the heat transfer distribution behind a small step in laminar hypersonic flow. A new parameter is proposed for such a correlation which shows that the heat transfer is dominated mainly by viscous effects when the gas phase Damkohler number is small and the surface is noncatalytic. Agreement with experimental data in both dissociated and undissociated flows, obtained in different types of flow facilities, is shown to be quite reasonable.
