| Abstract: | Nonisothermal three-velocity flow through porous media is investigated numerically with allowance for phase transitions. The modeling is based on the following common assumptions: it is possible to neglect the diffusive process of mixture component transport, longitudinal heat transfer due to heat conduction, and the transport of the liquid and gas phases as a result of the capillary pressure difference in the phases as compared with convective transport; the porous medium is in local thermodynamic equilibrium (equality of the temperatures, pressures and chemical potentials of the phases); and, moreover, the problems of heat transfer along and across the reservoir can be treated separately (Leverrier model).Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 78–85, September–October, 1989. |
