Title:
Evolution of perturbations in spreading viscous cylindric layer, subject to rotation and axial motion
An evolution in time of 3D picture of perturbations imposed on a radial-rotational spreading of a viscous cylindric layer moving axially is investigated. The parameters of the main deformation depend on both time and radial coordinate. A motion of the boundaries of the cylindric layer is given in the main process as well as in perturbed one. On the basis of the integral relations method [1], [2] applied to the linearized problem in terms of perturbations some sufficient estimates of exponential stability of the main process are derived.
