Hi. I want to simulate wall deposition using Lagrangian particle tracking, should the thickness of the first layer from the wall larger than the droplet diameter? Is there any appropriate ratio for that? Thanks guys!

Hi, I am simulating fluid particles in continuous vapor. Do you have any idea? Thanks!

Hi... To my knowledge there is no appropriate ratio for that. The particles are treated as sources for solving using PSI-cell method. So i think you can mesh according to your y+ and Reynolds number. regards
