Default No boundary layer
Posts: n/a
Hello, I just faced a ceratin problem, that is meshing an extremely complicated geometry of an experimental combustion chamber. As it is the early stage of its development, CFD results are needed to get a rough idea of velocities, pressure drops and so on. My question is whether complete elimination of boundary layer will still give some rough results? I do not know how wall functions will behave and so on and is it altogether possible to obtain the solution? Reason for my question is that the geometry is huge, computer resources highly limited and results do not need to be highly accurate. Thanks for any help.
