Abstract

pressure drop) all divided by the flow rate of the pure solution. In the treatment of the experimental data, two analyses are presented. (A) The flow of non-dilute suspensions of gas bubbles in non-Newtonian fluids through horizontal tubes are investigated. The investigation centered on the dependance of the flow rate on the properties of the suspension at set values of the pressure drop. A new technique was developed for the generation of suspensions of small, spherical gas bubbles in slowly moving highly visco-elastic solutions of water soluble polymer. Bubbles are produced by electrolysis on a stainless steel grid through which polymer solution flows. Experiments were conducted with aqueous solutions of polyacrylamide at two levels of polymer concentration. Flow-rate data are presented in terms of the relative change in flow rate, defined as the difference between the flow rate of the suspension and the flow rate of the pure polymer solution (at the same
