sir

i doing a project of multiphase flow to a company , in tat i have some douts, my thing is the flow of steam & water in that i dont know what is the dia of the water droplets & i tried with 1mm dia , weather it will affect the turbulece in the continous fluid & whether i have to apply turbulence transfer model(sato enhanced eddy viscosity) 2. while running solver it gives memory error i have 55,67,767 elements r there how to recover the problem , i increased the memory allocation facter as 2.5

iam having cfx5.6

Hi everyone:I got a difficult problem while learning CFX5.5 tutorial12.The problem as follows: For a rotor/stator (such as hydraulic turbine) problem,the rotation velocity is not known first.Why in the example gave a known velocity?
