Doing a study on the effects of erosion parameters on the erosion rate of a sharp 90 degree pipe bend. Keeping my Y+ value greater than 30 I need to undertake a mesh convergence study to decide a mesh to use. Can I use the turbulent flow solution as validation for the mesh sensitivity or does it need to be done until the erosion converges. Problem is that the number of particles injected needs to converge for each mesh that i study which is proving troublesome and inconsistent. At the moment I am just using a 2D model.
Any help on the matter would be great.
