Collision rates and collisional energy distributions within shock waves
Abstract
The direct simulation Monte Carlo method has been used to determine the collision rate and the distribution of relative translational energy between colliding molecules within strong shock waves. The results are compared with the corresponding theoretical quantities in an equilibrium gas. The objective was to determine whether the region of marked translational nonequilibrium within the wave needs to be taken into account in the interpretation of reaction rate experiments in shock tubes. A likely correction to relaxation distances is found to be of the order of ten times the translational shock thickness.
