Abstract :
Nonlinear equations of the dynamics of a spherical layer of fluid, which obeys the rheological law of Oswald, were received. The change in time of the gas bubble radius for different values of the non-Newtonian index was calculated numerically. Also the phase portraits of the dynamical system were shown.
