摘　　要：本文用ＳＩＭＰＬＥ方法对横掠顺排和叉排膜片管束周期性充分发展层流流动进行了数值模拟，得到了不同Ｒｅｙｎｏｌｄｓ数下的流动阻力系数和流动图象。计算发现，Ｒｅ＞９００，流动已进入自模化。Namerical Simulation by SIMPLE method is made for periodic fully developed fluid laminar flow in an inclined array and staggered array film-tube bank to obtain flow friction factors and flow chart under different Reynolds numbers and it is found that the fluid flow is automatic simulation for Re>900.

关 键 词：膜片管束 充分发展 数值模拟
