Abstract:
Drag reducing polymers are evaluated by their resistance against mechanical shear forces.Higher amounts of drag reduction as well sustainability under turbulent conditions make a polymer asan efficient drag reducer. This study compares the performance of two drag reducing polymers withlinear backbone under turbulent flow in a laboratory scale pipe line. Two commercially available watersoluble well-known polymeric agents, polyacrylamide and polyethylene oxide, were added to theturbulent flow of water. Variation of pressure drop in the pipe line was then measured for 2 hours tocompare the effect of diluted polymeric solutions with the one with water. Polyacrylamide showedbetter performance compared to polyethylene oxide in terms of both degradation and drag reductionpercentage. An experimental analysis with Response Surface Methodology (RSM) to the historical datawas then employed to analyze the data.
