Abstract: | Within present work, the whirl dynamics are reconsidered by allowing for the possibility of asynchronous whirl frequencies. The system is an asymmetric cylindrical of symmetry which is fixed in space. The equilibrium motion liquid may be superimposed on this equilibrium motion. Due to the Coriolis force, there are two frequencies for each nodal pattern. For our system, the angular speed vector of the container traces a circular path in a plane perpendicular to the axis of rotation. Thus our interest is in force rather than free vibrations of the liquid. Within present work the liquid is taken as being inviscid, and no assumptions arc made a priori about the nature of the radial and tangential velocities in the body of the liquid. Experiments completely corroborate the analytical results. |
