An Experimental Investigation of the Aerodynamics of a Disc Valve
نویسندگان
چکیده
The object of this study is a disc valve. In particular, the transient behaviour of the valve is studied as the valve moves from being fully closed and sealed to being fully open with steady-state flow of air established. The steady-state behaviour is well researched, the transient behaviour less so. A common assumption in valve design is that transient valve behaviour can be accurately represented by steady-state flow at fixed increments of valve lift. This assumption was shown to be incorrect at the early stages of valve lift by earlier work (1,3).

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...
