Hi,
I have recently applied Peric's codes to calculate the flow field of a thin channel. The boundary conditions are as follows: 1) west side is an inflow 2) east side is an impermeable wall 3) south side is symmetric plane 4) north side is a porous wall. for the condition 4) the U-velocity is calculated from no-slip condition and V -velocity at the porous wall is calculated from total mass conservation. The solution is calculated from colocated grid. The SIMPLE scheme does not give me converged solution despite i have changed the under-relaxation factors. Does and of you have any suggestions how i can improve this? Your feedbacks are much appreciated. thanks! newcomer_ to_ CFD |
