摘要： A pulsation dampener for receiving a fluid medium containing pressure pulsations. The pulsation dampener can include a body having an inner surface, an inlet, and an outlet, and a fluid path defined at least partially by the inner surface of the body. The fluid path can include a first chamber in fluid communication with the inlet and having a first cross-sectional area, a second chamber positioned adjacent the first chamber and having a second cross-sectional area different from the first cross-sectional area, and a third chamber in fluid communication with the outlet and positioned adjacent the second chamber opposite the first chamber and having a third cross-sectional area different from the second cross-sectional area. The fluid path can be configured such that the second cross-sectional area is greater than the first cross-sectional area and the third cross-sectional area.

摘要： A method of attenuating fluid dynamic pulsations that propagate through a flow of fluid at a convective velocity of the fluid, the pulsations having an organized vortical structure includes directing the flow to a pulsation dampener inlet having a first area and transitioning the organized vortical structure to a small-scale turbulent structure by squeezing the vorticies by passing the flow of fluid through a passage having a second area that is smaller than the first area, then rapidly expanding the flow of fluid by passing it into a chamber having a third area measured at an inlet of the chamber that is substantially larger than the second area. The method also includes discharging the flow of fluid from the chamber. The flow of fluid includes substantially attenuated fluid dynamic pulsations and acoustic pulsations that travel through the flow of fluid at the speed of sound.
