A finite-volume method for the prediction of turbulent flow in arbitrary geometries
A working method has been produced for calculating turbulent separated flows in complex geometries using arbitrary non-orthogonal computing meshes, which may be specified by the user in a pointwise fashion. Although. useful as it now stands, tests on the method suggest that there is scope for improvement, particularly in respect of accuracy, and efforts are now being made in this direction.
