Hi,
I'm trying to run a simple case of flow past 2D s1020 airfoil at Re = 100. I have used an O grid, running at 200x50, 400x97 and 800x200. At 1st, I used simpleFoam and the ans between the 3 differs by a bit. At aoa = 0deg, cl ~ 0.04, cd ~ 0.4 Next, I rerun the cases using pimpleFoam. At aoa = 0deg, cl ~ 0.2, cd ~ 4, altohugh it still very slowly declining. But the difference is still too much. The files are almost the same so which is this so? Any hint? Re 100 and AOA ~ 0, shouldnt the flow be steady? Thanks |
