nI am reattaching a slightly modified image of the one posted above. The centerline is the red line at the center shown below . It runs through the length (6MM) of the converging section.nAlso, what does getting peak velocities mean?. I mean wouldn't the peak velocity have to be 75mm/s at the outlet of the converging section? Would this error alter my morphology of the deposited plastic?. nI do not believe that the moving walls (parallel to the symmetry plane and outlet), from where the air is coming in has anything to do with this.nThanks for your inputs sir.n
