热萃取系统

The control equation consist of completely coupled deformation equation , seepage equation , conduction and convection equation of heat , which describe the reservoir non - liner performance . 2 , present the detailed strategy and methods to solve this mathematics model , the basic strategy as follows : regard the deformation equation ? seepage equation conduction and convection equation of heat as separate system , and solve the equation by coupling and iterative method ; disperse the control equation in the geometry field by the finite element method ( galerkin ) , and in the time field by the finite difference method : programme the computer program on this task ; when the solving , take the combinative measures of the thick and thin mesh ; successfully carry out the numerical simulation in vast 3d heat extraction system of hdr
2 、提出了高温岩体地热开发的固、流、热多场耦合数学模型的数值解法，其基本的求解策略是：将固体变形，流体渗流与温度场方程看成独立的子系统，耦合迭代求解；利用有限元离散( galerkin )方法将控制方程在几何域上离散，并用差分法得到时间域上的离散方程，并在此基础上，编制了相应的计算机源程序；有限元求解中，为减小边界效应的影响，在计算中采取粗细网格结合的方法，顺利地实现了高温岩体地热开发三维巨系统的数值仿真。
