| Outline of Final Research Achievements |
Firstly, fundamental procedure to simulate water-vapor two phase flow was established be means of finite volume method. The characteristic point of the study is that we introduced the geothermal element method and that the whole geothermal reservoir is simulated by the combination of the geothermal elements. Two phase sate in the rock was also visualized by X-ray CT method. Especially, new calibration technique was established using KI solution as a contrast agent, and it becomes possible to evaluate the real density distribution, such as water-vapor condition in pores.
