플래시증발현상은 개방챔버 내의 온도, 압력, 수위 그리고 배플 등에 영향을 받는다. 이 연구에서 PIV 실험은 최적의 배플 위치와 높이에 대한 개방챔버 내의 유동특성을 확실하게 시행하였다. 배플은 개방챔버 내의 재순환 흐름, 수력도약 그리고 유동특성에 상당한 영향을 주었다. 그리고 레이놀즈수의 영향은 미미하였다. 최적의 배플높이는 h/H=1.5였고, 최적의 배플위치는 개방챔버 내부 입구로부터 x/H=1.5부근 이었다.
Abstract
Flash evaporation phenomenon is affected by temperature, pressure and water level in the open chamber and Baffleetc. In this study, PIV experiments were conducted to ensured the flow Characteristics in the open chamber, and optimum bafflelocation and baffle height. Baffle had a considerable effect on the recirculation flow, hydraulic jump and the flow characteristicsin the Open chamber, and influence of Reynolds number was insignificant. The optimum baffle height was abouth/H=1.5. and optimum baffle location was x/H=1.5 from the inlet of open chamber.
