Backward Step:DPM

Hi All

I am trying to simulate multiphase using the discrete phase model over a backward facing step.The problem I am haveing is that the injection of particles don't seem to spread at all and continue in a straight line and don't enter the recirculation zone behind the step.

Is this a problem with the v-velocity component of the injection? This is unknown to me at the start of the simulation but I have set to 0.01 m/s (instead of default of zero)in the injection panel, however this produces a value 10 times to big in the flow field when compared with literature (0.1m/s).

Can anyone advise me on this matter?

Thanks
