bubble column tutorial's velocity above the free-surface

Hi guys,

Im confused about the velocity in the tutorial of compressibleTwoPhaseEulerFoam. See the image, it shows the UWater. I didnot do the experiment, but I wish the uwater above the free-surface tends to be zero. but it is not. Anyone can explain this to me?

Thanks.

And it happens to my case too, my inlet velocity is 0.2/s, but in the internal field, the max U can get to 5m/s. Is this normal?

In the tutorial, the inlet velocity is 0.2m/s. but the max(U) can get to 1m/s. is this normal?
