Hello everybody,
I am currently doing my master thesis, which is about analysing a vortex generator model that (hopefully) allows the computation of the vortex downstream a vortex generator without meshing the vane. I will try to explain the model briefly: Instead of meshing the vanes, a plane with azimuthal velocity is introduced at a certain streamwise position. If one sums this 2D vortex velocity field (v,w) with the unperturbed velocity field (u), on a flat plate for example, then a vortex similar to that downstream the vane can be created. (Where u is the axial velocity, v and w are azimuthal velocity decomposed in the cartesian coordinated. ) I have already the velocities v and w for each cell of the plane located at x/c =1, but now I cannot find any boundary condition that allows me to introduce a velocity field jump at this coordinate. I saw already examples with: - Groovy boundary condition with swirl at inlet. This however do not depend on the velocity field. - Fan and fixedJump boundary conditions. But these are just for pressure changes. I believe that it is possible to change fan boundary condition where the jump of U of each cell of the fan patch is read in a certain table. But I don't have any ideia how to do this, or if this approach makes sense. ![]() Can anyone help me please? Forgive me if the questions is to dull but this is the first project I do in openFoam. Thanks in advance ![]() |
