Rayleigh-Taylor instability of the radial motion of a rotating liquid shell
Abstract
Analytical and numerical investigations of the Rayleigh-Taylor instability of the radial motion of a rotating liquid shell are performed. It is assumed that: (1) the shell is homogeneous in the direction of the axis of rotation, (2) the shell material is an ideal and incompressible fluid, (3) the conditions are adiabatic, (4) the disturbances are potential, (5) the disturbances of all parameters depend harmonically on the angular coordinate, and (6) at the initial moment the shell rotates like a rigid body. A system of ordinary differential equations is obtained describing the time evolution of the harmonic fluctuations of the inner and outer boundaries of the shell.
