REENTRY PHYSICS

Abstract

For a diatomic gas, the kinetic energy in a hypersonic now is converted rapidly into translational and rotational energies through a shock wave, while vibrational degree of freedom of the molecules is excited relatively slowly. As a result, the translational temperature reaches a very, high value immediately behind a strong shock and then diminishes as the vibrational mode is excited. The effect or thermal radiation from this temperature spike is to broaden the shock structure and to induce disturbances ahead or the shock. The problem has been formulated and examined qualitatively. Quantitative results will be obtained by numerical computation.
