Translation nonequilibrium in a rapid expansion flow from a high temperature source
Abstract
Terminal parallel temperature of a rapid expansion flow into a vacuum was examined. It is shown that for a high temperature flow, the inclusion of a more realistic intermolecular potential with the repulsive term gives a more accurate prediction of the translational relaxation during the expansion. In a temperture range, 7000 to 10000 K, the measured terminal parallel temperature in an expansion flow of shock heated argon agreed with predicted values.
