uniform distribution of velocity
 

I AM TRYING TO MODEL INCOMPRESSIBLE FLOW IN A MICROCHANNEL.. THE MICROCHANNEL HAS A SECTION LIKE A TRUNCATED CONE TILL A DISTANCE 1.5MM AND THEN AN UNIFORM CHANNEL FLOW AFTER THAT UPTO 32MM. DOES ANYONE KNOW HOW TO GET A UNIFORM PROFILE OF VELOCITY AT THE CHANNEL AFTER SOME DISTANCE DOWNSTREAM GIVEN THE GEOMETRY. I AM OPEN TO SUGGESTIONS REGARDING THE USE OF OBSTRUCTIONS IN THE FLUID PATH... THANKS
