Flat Plate
4 Attachment(s)
Hello, Foamers,
I've been trying to plot the "Law of the wall" on a flat plate for quite some time now. However, I have problems to get the desired values in the turbulent area. I use both a BlockMesh and a mesh from StarCCM to get the result with OpenFOAM (Figure 1.). StarrCCM: 170042 Cells BlockMesh V1: 7200 Cells BlockMesh V2: 220000 Cells But in all cases I get the same wrong result (Fig2.). I calculated all calculations compressible as well as incompressible. As reference simulation I use the correct result of StarCCM+ and the literature. Now the question is whether it may be due to the boundary conditions (Fig3). I determine the velocity curves and the wall shear stresses with ParaFOAM. My analytical calculation of the wall shear stress corresponds to the result of ParaFOAM (Fig4). I would be very grateful if you could take a quick look at my case. Best regards Kevin |
