Patching region and Under Relaxation Factors
hi, i start to generate the model in 2d & further proceed to 3d model. I am trying to study the fluidization of solid particles with carrier gas, flow analysis & the profile within the mill including pressure distribution , velocity & volume fraction for both phases. How about 'patching' region in 2d & 3d models? What are the special attention i should give in setting the pressure, momentum, volume fraction, turbulant viscosity ratio etc. for convergence? thank you.
