CFD 해석을 이용한 막여과 공정 밸브의 개폐시간에 따른 유동 특성 = Flow characteristics according to the valve opening time of the membrane filtration process using CFD Analysis

다국어 초록 (Multilingual Abstract)

A device that opens or closes the passage of a fluid for the purpose of controlling the flow, pressure and temperature of the fluid in a pipe is called a valve. Hydraulic actuator is a primary component of the hydraulic valve systems. Actuators are installed on these valves to convert power into mechanical outputs such as force or torque to allow the loads of valves to be operated remotely or automatically controlled. As the opening and closing time of the valve varies depending on the type of actuator used, the characteristics of the pressure and velocity distribution depending on the valve opening and closing time are compared using computational fluid dynamics analysis. The flow characteristics of around the valve in the pipe and at the pipe exit were analyzed for the valves with opening times of the valves of 3 seconds and 7 seconds. The velocity and pressure distribution at the exit of the tube are almost the same regardless of the opening time of the valve.
