| Research Abstract |
In order to improve the mixing efficiency for liquid-liquid or liquid-powder, vibratory mixer using levitated fin by magnetically repulsive force of a pair of permanent magnet is developed. The levitated fin is excited by the outside magnetic force fluctuating periodically and performs reciprocating motion in cylindrical mixing tank. The restoring force acted on the levitated fin has strong non-linearity. This mixing system effectively utilizes a non-linear resonance of the fin. Effectiveness of the developed vibratory mixer was confirmed through the experiments and the numerical simulations.
