Solution is converging but have reverse flow on pressure outlet
 
Dear Friends,
Hi!
I am modelling a hydrodynamic journal bearing which is nothing but one cylinder rotating inside a stationary cylinder and there is a fluid flow thru annulus (which is @50 microns). I have modeled rotating member as a shaft(@3000 RPM) and stationary as bearing. The 50 microns lubricant film is meshed into 32 layers.
My solution is converging but i am facing reverse flow problem at pressure outlet. Is this reverse flow expected in such cases? or if not how to get rid of it?
Thanks in advance
