When unresolved CFD-DEM is used in coupling calculation, both fluid flow field and particles dynamic both are in time and space domains solves. The coupling time step (coupling number) and coupling region (CFD solution domain) directly affect calculation accuracy and efficiency. Therefore, through r...
