| Abstract: | Calculation has been made of the thermal effects attending nonresonant vibrational exchange in a molecular gas in a nonequilibrium state. Study has been made of the binary mixture, modeled as a set of harmonic oscillators of various frequencies. Vibrational exchange, the most rapid relaxation process occurring in the system, was assumed to completely determine the distribution of vibrational energy. It is shown that nonresonant vibrational exchange can lead to either heating or cooling in nonequilibrium states of the gaseous mixture. Calculation has been made of the amount of thermal energy liberated or absorbed in these processes.Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 2, pp. 20–23, March–April, 1975.The author would like to thank N.
