Abstract

The valve is used on control of flow in a ship. Flow coefficient of valve is very importance in the design of valve. In this paper, three-dimensional computer simulations by commercial code CFX were conducted to observe the valve type and to measure flow coefficient when valves with various angles and uniform incoming velocity were used in a piping system. By contrast, a group of experimental data is used to compare with the data obtained by CFX simulation to investigate the validity of numerical method.

밸브는 선박에서 유체의 흐름과 유량을 제어하기 위해 사용된다. 유량 계수는 밸브의 설계에서 매우 중요한 요소이다. 본 연구에서는 상용프로그램인 CFX의 3차원 컴퓨터 시뮬레이션을 이용하여 동일한 유속이 적용될 경우 밸브의 형과 밸브 열림 각도에 따른 유량 계수를 계산하였다. 그리고 실험 결과와 비교하여 CFX 시뮬레이션 해석을 통해 얻은 결과의 신뢰성을 검증하였다.
