Pressure and Heat Transfer Measurements for Hypersonic Flows over Expansion Corners and Ahead of Ramps. Part IV: Mach 8 Heat Transfer Data for Flows Ahead of Ramps, Part of an Investigation of Hypersonic Flow Separation and Control Characteristics

摘要

Pressure and heat transfer data were obtained for hypersonic flows over 40-degree expansion corners and ahead of ramps. Full and partial span ramps, having wedge angles up to 90 degrees, were tested at two locations on a sharp leading edge flat plate, with and without end plates. Pressure data were obtained for M = 5 for model length Reynolds numbers between 1.1 and 6.6 million. Both pressure and heat transfer data were obtained for M = 8 for Reynolds numbers between 1.1 and 3.3 million. (Author)
