An experiment was made in the wake behind a strip of screen in the uniform flow. The wake was excited by various kinds of sound introduced from a loudspeaker. One purpose is to compare the turbulent wakes created by various sounds. The close similari

Experiments on the randomization in a two-dimensional wake

Autor: Sato, Hiroshi, Saito, Hironosuke, Nakamura, Hiroshi

A two-dimensional wake was formed behind a fine-mesh screens placed perpendicular to the uniform flow, The transition process in the wake was observed by a hot-wire anemometer. The starting period of the process is the linear growth of small-amplitud

On selectivity of Karman-vortex shedding frequency

Autor: Takagi, Shohei, Atobe, Takashi, Ito, Nobutake, Kamono, Shinobu, Rikitake, Satoru

Wake structure behind an NACA0012 with no incidence was examined to scrutinize the frequency selection mechanism of growing disturbances at Re = 7,200 based on the wing chord and the free-stream velocity. Two different kinds of unstable disturbances,
