Hey Guys,
I hope that you are all fine. I have been working on an example about flow over a cylinder. My domain is at Rmax=10 and a cylinder radius at Rcyl=0.5 and properties of rho=1m3/kg, dynamic viscosity of 0.025 N.s/m2. I have done the grid convergence study successfully and obtained the drag coefficient at zero mesh spacing. After finishing the grid convergence, I have to prove that the pressure force is the dominant part in the drag coefficient. Even though simpleFoam provides the folder post-processing with file force in it, I am unable to filter that and prove what I mentioned previously. Is there any way to filter the data and prove that the drag coefficient comes mostly from pressure forces instead of the viscous force. I would be more than happy if someone of you could give exploitations. I am attaching the forcecoeffs.dat that I have obtained. http://www.mediafire.com/download/24...orcecoeffs.zip Thank you, |
