Dear All,
I am facing convergence problem in multiphase (eulerian-eulerian) problem Problem Description three phases: air, and two granular phases air enters from the bottom one slid phase is patched inside the domain second phase enters the domain via mass-inflow boundary condition at some height above the region where first solid phase is patched the velocities of two solid phases phases don't converge. despite lowering the under relaxation factors, reducing time step size.... In the beginning they converge, but when the two solid phases come together, there is problem.... Can someone please explain this and provide a possible solution to this problem thanks and Best Regards |
