Phase transitions in flow through a heat-conducting porous skeleton. (English. Russian original) Zbl 1200.76185
Fluid Dyn. 39, No. 3, 429-434 (2004); translation from Izv. Ross. Akad. Nauk, Mekh. Zhidk. Gaza 2004, No. 3, 85-90 (2004).
Summary: The features of one-dimensional seepage flows of a medium in the form of a liquid, vapor, or liquid-vapor mixture are considered. It is assumed that the temperatures of the medium and the porous skeleton through which it flows are determined both by the heat-conduction processes in the skeleton and the medium and by the phase transitions of the medium (evaporation or condensation). The phase transition fronts and their structure are investigated for a pure medium, i.e., a liquid or vapor but not a mixture, no at least one side of the front. Moreover, the possible existence of a form of flow, not considered earlier, in which in a certain region of space the thermodynamic state of the particles belongs to the phase transition interface between the pure state and the mixture. The flows are considered in general form without specifying the properties of the medium.
