  Drag Reduction Annular Flow with Poly Acryl Amide Additive

  By Rajendra Prasad P, Swamy Sagar, Penta Rao T, K Nagamalleswara Rao

  Abstract: Drag reduction studies have been showed in annular flow with polyacrylamide additive. The percentage drag reduction in annular pipe flow ranges between 85–98% as the diameter increased from 0.02 to 0.033 m. The percentage drag decrease of 89 to 98% is detected as the polyacrylamide concentration is varied from 50 to 200 ppm. The correlation for drag reduction and Reynolds number is presented here under DR = 2.06Re-0.037. Keywords: Drag …
