A Numerical Method for Calculating the Temperature Distribution in the Porous Geothermal Reservoir with Linear Flow

Abstract

The temperature distribution in the porous geothermal reservoir, in which the reinjection water flows linearly, is calculated by means of the method of shifting particles proposed by Jinno et al. in order to solve the solute transport equation. In the method instead of solving the heat and mass transport equation directly, the characteristic equations are determined and solved. Although there are some complexities in designing influence element meshes and locating points, numerical solutions obtained by the method show fairly good agreements with analytical ones for the two dimensional steady state heat and mass transport equation. The method is superior in accuracy to the conventional finite difference method.
