Experimental survey of influence factors to the possible possibility of surfactant solution

Abstract

   The decrease in drag of surfactant solution in turbulent flow is affected by many factors such as temperature, pipe diameter, counter-ion concentration, entrance. In this study, the focus was on investigating the effects of tube diameter and surfactant and counter-ion concentrations on the ability to reduce the resistance of surfactant solution in a circular cross-section. Experimental results are used to discuss the applicability of the reduction of drag resistance of surfactant solutions under different conditions
