Hypersonic convective heat transfer over 140-deg blunt cones in different gases
Abstract
Large-angle blunt cones, with various corner radii, were tested in dissociated air, CO2, and CO2-Ar gas mixtures. These experiments were conducted at angles of attack from 0 to 20 deg. The heating distribution data and how shock-waved geometry were obtained during the cone's exposure to the three gases. The data can be used to partially validate two-dimensional (2-D) axisymmetric and three-dimensional Navier-Stokes solutions of the heating distribution over a 140-deg blunt cone in a simulated Martian atmosphere. The predicted heating distribution over the cones and estimated bow shock standoff distances using a 2-D axisymmetric Navier-Stokes code were compared with test data taken at zero angle of attack.
