Abstract: 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.

摘要： 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%.
