Autor: Hiroyuki IWAMOTO, Muneharu SAIGO, Katsuo INOUE, Kohei YUGE, Hiroshi KATO

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 87, Iss 902, Pp 21-00199-21-00199 (2021)

This paper deals with the impact of dropped hollow rubber spheres against a planar surface. Hollow silicon rubber spheres are used as the impact source of the measurement of the floor impact sound insulation of buildings, but the impact characteristi

Finite Element Analysis of Acoustic Streaming in a Kundt Tube with Artificial Ridge Boundary

Autor: Kohei Yuge, Yuji Wada

Publikováno v: 2018 IEEE International Ultrasonics Symposium (IUS).

Acoustic streaming near artificially prescribed ridges is simulated and discussed to understand the mechanism of Kundt tube powder-ridge generation. A viscoacoustic harmonic finite element analysis (FEA)and a static-fluid FEA are coupled using an aco

Analysis of ultrasonically rotating droplet using moving particle semi-implicit and distributed point source methods

Autor: Kentaro Nakamura, Yuji Wada, Hiroki Tanaka, Kohei Yuge

Publikováno v: Japanese Journal of Applied Physics. 55(Number 7S1)

Numerical analysis of the rotation of an ultrasonically levitated droplet with a free surface boundary is discussed. The ultrasonically levitated droplet is often reported to rotate owing to the surface tangential component of acoustic radiation forc
