热采数值模拟的快速自适应组合网格方法

A METHIOD OF FAST ADAPTIVE COMPOSITE GRID FOR THERMAL NUMERICAL SIMULATION

本文用快速自适应组合网格方法（ＦＡＣ）和逐次收据方法分别计算了一个三维、三相、二组分的热采数值模拟。计算结果表明，ＦＡＣ方法和逐次收缩方法的结果接近全局加密网格上的结果（其中ＦＡＣ的结果更为理想），而ＣＰＵ时间仅分别为后者的２２．３５％和１０．８％。

Applications of the fast adaptive composite grid methoe (FAC) to the numerical simula-tion of the thermal process are studied. A model promem of the thermal process with threedimensions,three phases and two components are computed by (1) the FAC method ; (2)method with successive constriction and (3) finite difference method with uniform grids. Theresult shows that the CPU time used by the former two methods are 22. 35% and 10.8% ofthe latter one, while the computing results are comparable.
