Analysis of coupled heat transfer for fractured rock seepage

This paper takes the coupling effect which between fissure water-pore water and temperature field as the research object,use finite volume numerical method to dispersed solving for heat and fluid flow control equations,Set up six kinds of flow rate plans for fissure water-pore water,gives part of the dimensionless temperature field,and analyzes the reason of the heat transfer and flow.The analysis result shows that: the heat and mass transfer which caused by fissure water-pore water in rock is plays an important affect for temperature field distribution of fractured rock;When happening underground fissure water-pore water seepage and-the heat transfer in the fractured rock,it will produce coupling effect between the seepage and temperature field;the water penetration speed in fissure is the main factor which effects the temperature of rock,and the pore water penetration speed is the secondary factor,temperature difference mainly happening in the boundary layer place of fracture water.
