Application – Computer Simulation of Flow around a circular cylinder
Two Dimensional problems
Flow around a circular cylinder
Problem Description
Air flows across a cylinder with the uniform velocity 0.003ms in the wind tunnel. The length of
the wind tunnel (fluid domain) has 25m long and 10 m height. The |鞍重股份股票 diameter of cylinder is 1m.

flow velocity
4. No Heat transfer
5. Neglect the gravitational force
6. Constant air density
Pre-processing stage
In this stage, we implement the “ICEM CFD” to perform the pre-processing work. The basic
steps as follow:
1. Establish geometry model
2. Block the parts
3. Generation the O grid
4. Mesh the model and check quality of mesh
5. Extrude the mesh
6. Reset the BC’s (boundary conditions)
7. Output to CFX5.7.1
