研究タイトル - Investigation of Gas-Liquid Two-Phase Flow Mechanisms in Microscopic Fractures under Reservoir In-Situ Thermo-Pressure Conditions
- 研究概要
- Due to the widespread presence of water presenting both gas and liquid phases in the fissures of high-temperature rock formations during the development of geothermal energy. The conversion and movement of these two-phase flows create a circulation that transfers geothermal energy out of the formations. When gas and liquid flow, the interface becomes unstable due to stress, temperature, and fracture characteristics. Accurately describing two-phase flow in fractures is essential for improving geothermal energy development efficiency and significantly increasing energy utilization. Therefore, my main research direction is to investigate gas-liquid two-phase flow in rock fractures during geothermal energy extraction after permeability enhancement. I plan to use laboratory experiments, theoretical calculations, and numerical simulations to explore gas-liquid displacement under various stresses, temperatures, and fracture distributions. This helps to determine optimal geothermal extraction modes under different conditions to enhance geothermal development efficiency.。
