摘要
运用有限分析法求解Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，获得了二维突扩管流的数值解。对于雷诺数为２５，５０，１００，１５０，２００的来流，预报的流动图谱具有相似性。
A numerical solution of two dimensional channel flow with a sudden expansion is obtained by solving the Navier Stokes equations according to the finite analytic method.The flow patterns predicted for the free flow with the Reynolds numbers, Re ,of 25,50,100,150 and 200.Satisfactory results are obtained as well for the recirculation zone and the re attachment length.
