摘要：

The influence of the asymmetry of the perturbations on the instability of viscous incompressible flow originated by a circular cylinder performing harmonic oscillations around its axis is investigated in the linear regime. The critical values of the Taylor number (based on the amplitude of the cylinder tangential velocity and on the thickness of the basic flow) and of the axial wavenumber are found to increase monotonically as the asymmetry parameter (azimuthal wavenumber) increases. This result agrees with previous experimental observations of the author. © 1979 Birkhäuser Verlag.
