EFFECTS OF NONEQUILIBRIUM AND MASS TRANSFER ON A BLUNT OGIVE PRESSURE DISTRIBUTION

Abstract

Pressure distributions over a spherically blunted ogive were computed for perfect (gamma = 1.4) gas, equilibrium air, and nonequilibrium inviscid outer flow fields with nonreacting and reacting boundary-layer flow fields. The effects of surface mass transfer and displacement were also included in the nonreacting flow field studies. The results show that for a short (15 nose radii), blunt body at the altitude and velocity conditions considered, the effects of (inviscid and viscous) chemistry on the surface pressure distributions were from about 10 to 20 percent, and the effects of displacement and mass transfer were less than 10 percent in general.
