Dear everybody,
I'm working on a simulation where I have a deforming wall. It is actually an airfoil with a deforming leading edge (the law depends of the flow condition). I would like to know if there is a function / tool in OpenFoam (2.2 if possible) able to keep the boundary layer next to the wall intact and send the deformation in the domain. I know that Fluent uses a 2 zone definition to do so. The first zone next to the wall follow the deformation while the second zone takes the deep compression / extension deformation. In my case the boundary layer is quite important and I need to use a y+ < 1. I know use this options for the dynamicMeshDict: Code:
dynamicFvMesh dynamicMotionSolverFvMesh; motionSolverLibs ("libfvMotionSolvers.so"); solver displacementLaplacian; displacementLaplacianCoeffs { diffusivity inverseDistance (wall); } Does anybody have experience in this kind of simulation ? |
