Master equation study of hydrogen relaxation using complete sets of state-to-state transition rates

摘要: The complete sets of state-to-state transition rate coefficients for both target and projectile molecules are derived from the predicted response surface designed by ordinary Kriging model. A system master equations is constructed bound-bound bound-free transitions with these coefficients, rovibrational number densities numerically evaluated implicitly integrating a equations. In equation studies, relaxation rotation vibration modes, density relaxation, reaction average rotational vibrational energy losses due to dissociation each considered in strong nonequilibrium conditions. coupled one-dimensional flow analyze relaxations H 2 post-normal shock nozzle expanding flows. flows, mode slightly faster or almost similar mode. modes seem be frozen.
