Abstract

Questions of the dynamics of bubbles in a liquid are connected with problems of cavitation [1]. In connection with cavitation phenomena in non-Newtonian media, in particular in polymeric liquids [2, 3], a study is made of the pulsations of a bubble in a polymeric liquid with an exponential rheological law. The equation of the motion of the boundary of the gas cavity is integrated numerically; here, the cases of pseudo-plastic and dilatant liquids are discussed separately. The results obtained can be used in the analysis of acoustical cavitation in aqueous solutions of polymers.
