An Experimental Investigation of the Simultaneous Effect of Micro and Nano Polymers on the Hydrodynamic and Thermal Properties of Turbulent Flow in a Horizontal Pipe

In this paper, the simultaneous effect of micro and nano-sized polymers on the hydrodynamic properties of turbulent flow (including pressure lose and friction coefficient) in a horizontal pipe at different Reynolds numbers studied experimentally. In this article, partially hydrolyzed polyacrylamide polymer is used as superfloc A110. In order to perform the comprehensive analysis, experiments were investigated with different concentrations of micro and nano-sized polymers and impact of various conditions on the pressure lose and friction coefficient. The results show that the addition of micro-sized polymers particles up optimum concentration (0625/0% by volume) reduced the friction coefficient. Also adding the nano-sized polymer particles to the solution containing the micro-sized polymer particles at the same time, the friction coefficient is reduced by about 58%. With increasing the temperature of solution up to 30 ° C drag reduction improved.
