Abstract
An open geothermal system consisting of injection and productive wells is considered. Hot water from production well is used and became cooler, and injection well returns the cold water into the aquifer. To simulate this open geothermal system a three–dimensional nonstationar mathematical model of the geothermal system is developed taking into account the most important physical and technical parameters of the wells to describe processes of heat transfer and thermal water filtration in a aquifer. Results of numerical calculations, which, in particular, are used to determine an optimal parameters for a geothermal system in North Caucasus, are presented. For example, a distance in the productive layer between the point of hot water inflow and of cold water injection point is considered.
