The Effect of Polymer Additives on the Cavitation Threshold of Water
Abstract
The effect of the polymer additives Polyox and Guar Gum on the acoustic cavitation threshold of water was studied as a function of polymer concentration and dissolved gas content. Cavitation thresholds were measured for water and different concentrations of Polyox and Guar Gum at various dissolved oxygen concentrations, using an ultrasonic technique. In this study, poor agreement was obtained for theoretical predictions based upon growth of a free air bubble, and good agreement was obtained for a theory based upon cavitation nucleation from gas trapped in a crevice in a solid impurity present in the liquid. It was discovered that previous explanations of the effect of polymer additives on the cavitation threshold are incomplete and need to take certain physical parameters of the liquid into account as well as the mode of cavitation nucleation.
