problem in setting up BC's
 

Hi,

i am carrying out flow analysis. The working priciple is that a circular disc is placed inside a cylider.

flow inside cylinder is tangential somewhere at top of cylinder ( left to right ).

outlet is axial. i.e, four outlets are there at some distance from center of disc.

i new rotation of disc in rpm, velocity of fluid at inlet. at exit i have given gauge pressure as zero.

are these Boundary condition's are ok.

i don't know how to send an attachment in this form, else i could have mailed the geometric model.

thanking you all, san
