Mach 3 three-dimensional boundary layer turbulence transport properties on a spherically blunt cone
Abstract
Three-dimensional boundary layer measurements were carried out on a 7-degree semi-vertex angle conical body configuration for angles-of-attack of 0 deg, 2 deg, and 4 deg in the NSWC Supersonic Tunnel Number Two. Tests were conducted at a freestream Mach number of 3 for a nominal freestream Reynold number of 2.3 x 1000000/ft (7.5 x 1000000/m) on a cone with a nominal 22% spherically blunt nose. Measurements of the three mean velocity component, turbulence, intensities, and Reynolds stresses were obtained at various circumferential locations around the body for one axial station using a 3-D Laser Doppler Velocimeter system. In addition, surface Preston probe and static pressure measurements were obtained at five axial stations along the body. The effects of angle-of-attack and model roll position on the three-dimensional mean velocities, boundary layer turbulence properties, and surface parameters are discussed herein.
