HYPERSONIC INVISCID AND VISCOUS-FLOW OVER A WEDGE AND CONE

An analysis of hypersonic flow over a wedge and cone is developed that is based on hypersonic small-disturbance theory in combination with l aminar boundary-layer theory. The parameters that determine the flow a re the ratio of specific heats (=1.4), the freestream Mach number, whi ch ranges from 4 to 10, the wall half-angle, equal to 5, 10, or 15 deg , a wall to freestream temperature ratio, equal to 1 or 3, a Reynolds number (=10(6), and a geometric parameter that is zero for a wedge and unity for a cone. All results are nondimensional and in a convenient form for establishing trends or for comparisons with experimental or C FD data. Results are provided for the inviscid surface values of the p ressure, temperature, and Mach number; wave and viscous drag coefficie nts and several heat transfer coefficients; the maximum temperature an d its location inside the boundary layer; and a variety of viscous and thermal boundary-layer thicknesses. The independent parameter is the freestream Mach number; the dependence on the wall to freestream tempe rature ratio and a Reynolds number are explicitly given.
