Mathematical Modeling of the Hot Steam-Water Mixture Flow in an Injection Well
In this paper, for the problem of pumping heat-transfer agent into an oil reservoir, a mathematical model of the processes occurring during the movement of a hot steam-water mixture in an injection well has been proposed. This model takes into account phase transitions occurring in a two-phase mixtu...
