Strong Subsonic Condensation of Polyatomic Gas

The effect of temperature on correlations in the Knudsen layer under conditions of strong subsonic condensation of a polyatomic gas is investigated. The method of moments is used to demonstrate that the dependence of pressure outside of the Knudsen layer on the flow temperature at a fixed value of the Mach number has a maximum. The limiting dependences of pressure on the Mach number are obtained for low and high values of flow temperature.__________Translated from Teplofizika Vysokikh Temperatur, Vol. 43, No. 4, 2005, pp. 601–605.Original Russian Text Copyright © 2005 by A.
