Hello,
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 Diameter: 0.003 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? thx |
