Abstract

During the past three or four decades, the characteristics of turbulent flow have been studied extensively because of their scientific and academic importance. This research deals with the periodic flow oscillation without swirling flow in a 180 degree circular tube using hot wire anemometry, microphone and accelerometer. The frequency regions are observed through the structured oscillation from spectrum. This work carried out to measure the sound level for each Reynolds number, $6{\times}10^4$, $8{\times}10^4$ and $1{\times}10^5$ respectively at the test tube without swirl flow.
