Abstract:
In this paper, we study experimentally the effect of the geometry parameters of a saw‐tooth surface and a micropart on the motion of the micropart. The experiments are performed for a range of the saw‐tooth pitch p , micropart length l , and exciting frequency f applied to the surface. By the use of particle tracking velocimetry method, we obtain the time‐dependent velocity and then the ensemble‐averaged velocity of the microparts. The results show that the velocity of the micropart increases up to a certain value of pf and then decreases with increasing pf . The widths of the profiles are similar for the same value of the relative scale l / p but the peaks of the profiles are slightly larger and the profiles are shifted leftward for larger pitches of the saw‐tooth surface. It implies that the motion of the micropart depends more on the characteristic surface velocity pf than on the relative scale l / p and that a larger pitch of the sawtooth creates a larger asymmetric force on the micropart. © 2013 Institute of Electrical Engineers of Japan.
