Book excerpt: Laminar boundary-layer separation induced by a flare on a cylindrical body of revolution has been experimentally investigated in the Mach number range of 2.0 to 5.5. The Reynolds number range (based on boundary-layer thickness) was 1x103 to 30x103. Geometric variables were nose shape, cylinder length, and flare angle. Test variables were Mach number, Reynolds number, and heat transfer. The purpose of the investigation was to determine which of these variables most influence laminar boundary-layer separation on a cylinder-flare configuration and to provide data that will aid in the prediction of laminar separation.
