According to the basic equation of two-dimensional laminar flow and combining with the sudden expansion boundary,the steps for developing the visualization program of numerical simulation of the two-dimensional laminar flow are introduced in details and the solutions of some key steps are given by using Fortran for numerical computation and using VisualBasic for developing the application program.At the same time,linear interpolation is used to deal with the stream function contour and grid node.The visualization program is ideal comparing with the similar softwares from abroad.
