内容記述 | The steady flow characteristics around a valve plate installed at the exit of a rectangular duct and the fluid force acting on the valve plate are studied experimentally, in order to determine the flow characteristics around flap valves, which are usually used to prevent reverse flow at the stop of pumping in large-size low-head pumps. It is shown that the outlet flow has strong three-dimensionality with large lateral leakage from both sides of the valve plate, which results in that the outlet flow has the characteristics of a discontinuous separated flow rather than that of a jet flow. Empirical equations for pressure drop coefficient and moment coefficient around the plate axis are obtained, as well as a simple approximate method for estimating fluid force acting on the plate. The influence of an obstructing wall near the valve exit upon valve performances is also determined. | |||||
