Application of FLUENT Software in the Simulation of Flow around a Cylinder

摘要：

Uniform flow around a mounting cylinder is simulated with the application of FLUENT software while Reynolds number is 20,40,100. Stream function and velocity vector distributions are indicated. The results show that a series of construction appears as Reynolds number increases. When Re is around 40, flow pattern change: there is a pair of mounting vortex with Re less than 40; on the contrary is becomes unsteady and vortex expand, slough, generate again until two row of periodic swing and overlap vortex form. Compared with experimental result, it is confirmed that FLUENT can well predict flow structure.
