Transient Behavior of a Springless Flapper Valve: Closing Motion

Abstract: The closing of a springless flapper valve was investigated in order to gain a better understanding of the transient behavior of the valve. An experimental investigation included simultaneous measurement of pressure and flapper velocity. An analytical investigation included the development of a model to predict the closing of the flapper valve. The flapper closing was experimentally determined to require from 18 to 24 percent of a cycle, and the model predictions were in good agreement with experimental data fo… Show more

“…The viscous model used is mostly linear viscous model which assumed that the friction was proportional to the velocity of the flapper. Dhar (1980), Lee, Van Essen, Morel and Zinn used the viscous model; Temple used this model for the closing process of the valve [6,7].…”
