On incompressible viscous fluid flows with slip boundary conditions

[摘要] We consider stationary and nonstationary problems of viscous incompressible fluid flows with slip boundary conditions in a rotating bounded domain. We show a geometrical representation of the slip conditions where principal curvatures of its boundary surfaces are characteristic coefficients. When the domain is axisymmetric, it is proved that a steady flow exists if external force f in equations of motion is orthogonal to rigid rotational flows, and that a nonstationary flow converges to a steady flow depending on its initial flow as time tends to infinity, if f is independent of time and orthogonal to rigid rotational flows and if the L-2-norm of f is sufficiently small.
