Flow past cylinder with an exact solution?
Dear all,
Does anybody know if there is an exact solution for some flow past circular cylinder case? I need such a problem to test my numerical method, but I could not find it. To be honest, I am not very familar with CFD. I know there are many CFD experses here. Your help will be most appreciated. If you know where I can find it or you have one at hand and you are willing to help, please email me at annie_sunyh@yahoo.com Thank you very much! Anna |

Re: Flow past cylinder with an exact solution?
Dear Anna,
The inviscid flow past a circular cylinder is a simple potential flow problem that has an exact solution. You can find it in any basic text book on Fluid Dynamics or search for it in google. If you want a book in particualr, look into Kundu and Cohen's Fluid dynamics book. As a remark, the exact Cp on the cylinder varies as 1-4*sin^2(theta). This compraison is good enough to validate any incompressible solver or a compressible solver below Mach 0.3. I am not sure what you want to verify but I hope this helps Regards, Ganesh |
