I faced the following difficulty.
I switch off the dispersed phase volume fraction at inlet . That is inlet alpha = uniform 0 and also the dispersed phase velocity . I keep my continuous phase velocity Ub = 0.1 m/s . Continuous properties are rho = 1000 kg/m3 , nu = 1e-06 m2/s . This means now i am studying single phase flow . I compared the results to simpleFoam results and have found a problem with the velocity plots in the plane z=0.2 on the same timestep . Specifically on the line joining (0 0.5 0.2) and (1 0.5 0.2) . Can someone help me resolve this issue ....
My blockMeshDict is as follows :
