| Abstract: | Three-dimensional unstructured multigrid method for solutions of unsteady incompressible viscous fluid flow was developed and validated numerically. In simulation, the node-centered finite volume scheme for numerical integration of the Navier-Stokes equations was used for space discretization. A sample problem for the flow over a cylinder with Re=100 was successfully calculated. The results are in good agreement with given computation and experiment solutions from abroad.This method is of accuracy and validity. |
