Thermobaric calculation of a steam-thermal borehole

Thermal Engineering Aims and scope Submit manuscript

Abstract

A procedure is proposed for carrying out an approximate analytical calculation of pressure and temperature along a vertical borehole for thermal water with a temperature of 150–320°C taking into account its phase transition into steam. It is shown that both a single-phase flow mode for water and a two-phase flow mode for a mixture of water and steam can appear in the borehole under certain conditions.
