Default Multiphase Eulerian & UDF
Posts: n/a
Hi! I am trying to tune up the Syamlal O' Brien drag law using a UDF like the "custom drag law" in the examples. The problem is that I cannot figure out how should I calculate the constants which are used in the A and B factors calculation. I tried to balance the drag force with the weight in the particles of one cell but I did not succeed. Can anybody give me a hint?

Thank you,
