Ma. Brutyan et Pl. Krapivsky, COLLAPSE OF SPHERICAL BUBBLES IN FLUIDS WITH NONLINEAR VISCOSITY, Quarterly of applied mathematics, 51(4), 1993, pp. 745-749
An analysis is given of the collapse of a spherical bubble in a large
body of a viscous incompressible fluid with strain-dependent nonlinear
viscosity. Two types of asymptotic behaviors are found analytically,
namely the collapse over finite time and viscous damping over infinite
time.
