High-Speed Observations of Highly Erosive Vortex Cavitation 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...

High Speed Imaging of Cavitation around Dental Ultrasonic Scaler Tips

Cavitation occurs around dental ultrasonic scalers, which are used clinically for removing dental biofilm and calculus. However it is not known if this contributes to the cleaning process. Characterisation of the cavitation around ultrasonic scalers will assist in assessing its contribution and in developing new clinical devices for removing biofilm with cavitation. The aim is to use high speed...

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

A Review of Recent Studies on Simulations for Flow around High-Speed Trains

Fluid flow around bluff bodies occurs in numerous fields of science and engineering, such as flows pass vehicles, cables, towers and bridges. These flows have been studied experimentally and numerically for the last several decades. The investigation of flow around high-speed trains is an important application of bluff bodies. Fluid flow, aerodynamic forces and moments, separation and wake regi...
