Local pressure drops in the flow of water with micellar additives
Abstract eng: We have studied the influence of three cationic surfactants Arquad S50, CTAB and CTAC on three different types of local pressure drops. Experiments were done on a closed hydraulic loop with the range of Reynolds numbers from 1,600 to 23,000. Four different solution concentrations were investigated. Even though all three tested additives show similar drag reduction in the straight tube, there is a substantial difference in effectiveness at local loses.
