Abstract: | Results of numerical calculations of condensing vapor expanding into a vacuum and in a supersonic conical nozzle are presented. Nonequilibrium homogeneous condensation is compared with the theory of determining parameters. It is proved that equality of the determining parameters ensures the unity of the course of such processes in different devices. The influence of unsteady nucleation on the maximum supercooling was also investigated. All the calculations were made for water and nitrogen vapors.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 152–156, March–April, 1986. |
