ICEM CFD
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.

Assumption and Boundary Conditions:

1. 2 dimensional problems
2. Steady state condition
3. The uniform 龙电b股 flow velocity
4. No Heat transfer
5. Neglect the gravitational 股票600348 force
6. Constant air density

Pre-processing stage
In 股票002538this 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

士别三日当刮目相待啊，这刘大军，现在居然已经混到了连长了？这才几年的时间？ 虽然己方的69坦克也卖出去了一百万，但是，那是特殊情况，战争中的交战双方急需而已，以后等到这款坦克研发出来之后，再投向国际市场，那是要竞争的。 他们不急。 但是，这个重大的项目，一机厂自己是不能拍板的，还得上级同意才行，于是乎，就可以拿着这个来卡一机厂了。 这是一款风冷柴油机！ 谢惠民无奈地苦笑，他自然知道秦振华是在干什么，这用的是激将法，故意激将大家伙呢。 工厂已经被法院给查封了，毕竟早就资不抵债了，而他作为厂长，也无法再进去，只能是在厂子外面看看，看着那围墙已经斑驳起来了，看着那野草正在肆意地生长着，就像是一个老人一般，已经到了濒临死亡的时候，再也起不来了。
