Simulation of Single-Phase Non-Isothermal Filtration of Groundwater Circulation Systems
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2017, Vol 21, Issue
Abstract
To improve technical and economic performance indicators of geothermal plants, it is necessary to conduct comprehensive research using numerical methods. In this paper, there is the mathematical model of single-phase non-isothermal filtration and the proposed method of modeling the movement of the temperature front of non-isothermal filtration based on the continuity of fluid flow. This phase will identify the main technological parameters of geothermal installations (temperature and pressure of heat carrier), to predict thermal processes in underground circulation systems and determine the operating mode that will ensure efficient extraction of geothermal energy. The numerical solution of non-isothermal filtration by presented methods and verification of received data will be done in future studies. Practical value consists in possibility of using the results by research and design establishments during the optimization of the parameters of geothermal installations
