The authors experimentally observed the pressure flow of non-Newtonian fluids between eccentric double cylinders with the inner cylinder rotating. Experiments were carried out to measure the pressure gradient, the angle of the secondary flow region and the pressure distribution on the outer cylinder using aqueous solutions of hydroxy ethyl cellulose (HEC:). Results are summarized as follows: 1) Axial flow rate was enhanced by the rotation of inner cylinder. Denote the axial flow rate Qs and Q, respectively with the inner cylinder stationary and rotating. Then the larger was the difference between Q, and Q, the larger was the effect of eccentricity.2) The angle of the secondary flow region increased with decreasing number of inner cylinder rotation and increasing axial pressure gradient. 3) Distribution of pressure on outer cylinder was affected by the axial flow rate, radius ratio and eccentricity. 4) Experimental results agreed well with numerical predictions. Thus the reliability of the numerical method used in the previous paper was confirmed.

This paper proposes a new magnetic plane motor capable of rotation by the resonance energy of double-cantilever beam model excited by an electromagnetic force. This magnetic plane motor has two double-cantilever models, and the rotational direction is able to change by changing of the vibration mode. Basic characteristics of a prototype for the magnetic plane motor, such as rotational speed, output torque and efficiency were determined experimentally. Experimental results demonstrated that the rotational speed of 8.1 rpm was obtained with output torque of 0.07 Ncm for the magnetic plane motor having double-cantilever model. The output torque characteristics of the magnetic plane motor with two double-cantilever models improved 200 percent compared with double-cantilever model.
