FSI- Pipe- uniform velocity profile inlet
Join Date: Apr 2010

I am running a FSI calculation on software is developed by my lab members. I am trying to run a pipe with a uniform velocity profile at the inlet but I am getting leakage in the flow by 11%.
the another problem is the maximum velocity is not twice of the mean velocity even if the cylinder is long enough for full development.
lenght of cylinder: 0.02 meter
inlet velocity (mean velocity): 0.1
Rho: 1000 kg/m3
Mu: 0.003 kg/m.sec
outlet boundary: free outlet
any idea about why I am getting this leakage?
when I try to apply a parapolic constant velocity profile in the inlet
I dont get those problems.
any one can help?
