How to see the effect of initial velocity

I am using reinitialized mass-conservative level-set method to study multi-phase flow problem.

I am using global equations to assign initial velocity (u(t0) and v(t0)) and apply them in
physic--sub-domain--init as initial for (u(t0) and v(t0). However, it seems like that
there is no effect due to initial velocity, which means that the results are the same as that
when initial velocity (u(t0)=0 and v(t0)=0).

Any suggestion on how to implement non-zero initial velocity.
