Abstract : The investigation extends existing low-Reynolds-number hypersonic flow theory to include mmagnetic-field effects. It is found that a small magnetic field of the order of 1000 Gauss or less reduces both heat transfer and skin friction in high-altitude flight, but increases shock standoff distance. The strength of magnetic field required is attainable by a permanent magnet. Increasing the wall temperature tends to produce higher values of both the heat-transfer and the skin-friction parameters. As flow approaches a merged-layer regime, the effectiveness of a magnetic field diminishes. (Author)
