Investigation of the parameters of a centrifugal pump working with a surfactant drag-reducing solution

Abstract

Flow resistance can be significantly reduced by adding a surfactant to the flow. As the flow resistance decreases, the pump performance also changes. In this study, the characteristic curve of the centrifugal pump was determined experimentally. The test was performed on solutions with different surfactant concentrations of 200 ppm and 400 ppm. The experimental results show that the total head of the pump for the case of a surfactant solution is greater than that when working with tap water. The efficiency of the pump for surfactant solutions also increases, but the shaft power for the case of surfactant solutions decreases compared to that for tap water.
