Abstract:
1. 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, the method comprising: directing the flow to a pulsation dampener inlet having a first area; 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 instantaneously expanding the flow of fluid by passing it into a chamber having a third area measured at an inlet of the chamber that is larger than the second area, the third area being the largest area within the chamber; and discharging the flow of fluid from the chamber via a contracting flow path, the flow of fluid including attenuated fluid dynamic pulsations and acoustic pulsations that travel through the flow of fluid at the speed of sound.
