裂隙岩体流热耦合的三维有限元模型
3D finite element model of fluid-heat coupling heat-transfer in fracture rock
摘要
Abstract
Based on heat-transfer and seepage theory, a 3D mathematical model of fluid-heat coupling heat-transfer in fractured deep rock has been developed. Temperature field and seepage field distribution of fractured rock are described using heat-transfer and seepage differential equations. Combined the parameters with boundary condition, the numerical solution is obtained using numerical simulation. The result of numerical simulation shows that the heat transportation resulted from fracture flow has major impact on the temperature field distribution in fractured rock. The existence of fault zone and ground-water flow alters the original temperature field distribution in rock mass. The model reveals the heat convection transfer between rock and flow in rock fractures, simulates the temperature field distribution in rock mass, and achieves the step change from point to field study on temperature. The simulated result is in consistence with the actual situation. This demonstrates that the proposed method is feasible for studying fluid-solid coupling heat-transfer in rock mass.关键词
