Abstract

The finite element method is used to visualize the development of flow pat­tern and temperature distribution in two-dimensional liquid-dominated geothermal system. This system is assumed as a homogenous porous host rock that is fully saturated by pure water. FEMLAB software is used to solve the differential equa­tions of flow and transport simultaneously. The different flow pattern and tempera­ture distribution appear with increasing simulation time.
