Ball valve 내부의 유동특성에 관한 수치해석

Valves has been used widely in various industries. Especially, a ball valve is on of the flow device most frequently employed in a pipeline system. There are many purposes for valve usage in a piping system. one of them is to control the flow rate. For a design of ball valves, it is important to know the characteristics of flows inside a ball valve. In this study, the computation fluid dynamics were conducted to observe flow velocity, flow coefficient and pressure distribution using CFX 11 according to the valve angles and uniform incoming velocity.
