Flow pulsation
WebThe conjugate rotor generates periodic flow pulsation, which results in vibration and noise of the unit. Therefore, the instantaneous flow pulsation of the pump directly affects the stability of the system operation. As shown in Figure 8, the red curve is the pulsating curve of the theoretical flow rate at the outlet of the rotary lobe pump. WebThe pulsation in a peristaltic pump is determined by many factors, such as: Flow rate – higher flow rate gives more pulsation. Line length – Long pipelines give more pulsation. Higher pump speed – higher rotational frequency gives more pulsation. Specific gravity of the fluid – higher fluid density gives more pulsation. Variations [ edit]

Webpulsation or flow phenomena. The gauge line starts at the orifice taps and ends at the transmitter, flow computer, or chart recorder connections. It includes any pipe fittings, … In fluid dynamics, a flow with periodic variations is known as pulsatile flow, or as Womersley flow. The flow profiles was first derived by John R. Womersley (1907–1958) in his work with blood flow in arteries. The cardiovascular system of chordate animals is a very good example where pulsatile flow is found, but pulsatile flow is also observed in engines and hydraulic systems, as a result of rotating mechanisms pumping the fluid.
