K-Epsilon for Vortex Shedding

Hi,
I was told that RKE is a better model to predict vortex shedding than SKE. I did try with RKE and I did get vortex shedding however my Cd value is not right. When I run my model with SKE, my Cd is right but I have not seen vortex shedding. My Re=10000 and I should be getting Cd=1.2 whereas I got 0.55 with RKE. I use EWT and y+~2. I hope someone can give me suggestion how to tackle the problem. I am more incline to use RKE since it gave me good vortex shedding however my Cd is wrong. Thanks. |
