Measurement of cavitation vibration and noise around a butterfly valve.

Investigation of the Flow and Cavitation in a Butterfly Valve

Since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. In reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. This paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...

Noise Reduction in Butterfly Valve Cavitation by Semicircular Fins and Visualization of Cavitation Flow

Recent Observations on Cavitation and Cavitation Noise

This paper is primarily concerned with the acoustics of traveling bubble cavitation around foils or headforms. We begin with observations of individual bubbles and the acoustic signals they emit, our purpose being to identify areas of research which would enhance our tlriderstaridirig of the history of individual bubbles. Then we present some riumerical integrations of the Rayleigh/Plesset equa...
