Abstract

Drag reduction by using certain polyoxyethylene alcohol non-ionic surfactants dissolved in water has been investigated experimentally. For these compounds it is proved that the mechanical degradation is reversible and the drag reduction is regained when shear stress is decreased. For solvent Reynolds number ranges from 103 to 2x105 in tubes of 6.17. 2.69 and 0.81mm, the effects of concentration electrolytes addition and mechanical shear on the drag reduction at/or near the could point temperature have been investigated experimentally. The drag reduction was found to be maximum at/or near the cloud point.
