Abstract
This research is to simulate two dimensional incompressible flow with spectral element method and splitting scheme. We utilize the unstructured element as our mesh type, triangular element is mainly used in this article. Base on these method, we develop a program to simulate two dimensional incompressible flow. Then using Kovasznay flow and transient flow which have exact solutions to verify the simulating program and relative numerical properties. Finally applying the developed program to obtain numerically some results of real fluidic field, include driven-cavity flow、sudden-expansion flow and cylinder flow. To verify the program via compare these results with relative papers, we find that the error of results is accepted.
