Research Abstract |
The rotational motion of the spin axis of a rotating object is called the "precession". It has been shown that a weak precession of a cavity can lead to strong turbulence of the confined fluid. Aiming to develop a new type of mixer without impellers on the basis of this feature of precession, we have conducted laboratory experiments and numerical simulations of flow in a precessing sphere and in a spheroid. We have then revealed the appropriate combination of control parameters, and the appropriate shape of the cavity to sustain strong turbulence in a precessing cavity.
