Two-phase flow in geothermal energy sources. Progress report No. 1: eight month period, October 1, 1975-May 30, 1976
A detailed parametric study of the major variables that affect the pressure profile in the geothermal well, and hence its performance, was conducted in order to identify and define the pertinent problems that require further experimental and theoretical investigation. The well and, in particular, its two-phase section were modeled on the basis of sound two-phase flow principles. A computer algorithm was developed for pressure profile calculations and simulation of well performance. The algorithm was used to study the effects of total mass flow rate, heat losses to the surrounding formation and void fraction on the pressure profile and the vapor and liquid production rates. In addition, several existing void fraction and frictional pressure drop correlations were evaluated in order to determine their applicability to geothermal systems. (MHR)
