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 …

Pulsatile flow refers to a type of fluid movement characterized by rhythmic variations in pressure and flow rate, often generated by devices such as roller or oscillating pumps, and has been …

Aug 14, 2025 · A pulsatile portal venous flow pattern is an abnormal form of portal venous flow and can result from both physiological and pathological causes. In well subjects, mild to …

In this review article we discuss current evidence on differences between continuous and pulsatile mechanical circulatory support, with a focus on clinical implications and potential benefits of …

Aug 2, 2025 · Pulsatile flow describes a specific type of fluid movement found throughout nature and engineered systems. It is a fundamental concept in both biology and physics, …

Classic texts in the field of analysis of flow in blood vessels have been written over the years and what these say is still valid today.

We are going to see exactly how and why fluid velocities do as they do in pulsatile flow. Unfortunately this is a purely mathematical/analytical endeavor; there is virtually no way …

May 29, 2023 · pulsatile flow Rhythmic, intermittent propagation of a fluid through a vessel or piping system, in contrast to constant, smooth propagation, which produces laminar flow.

Pulsatile flow is associated to a reduced ST-segment resolution and an impaired myocardial perfusion which may be explained by distal embolization and the release of vasoconstrictors. …

Flow solutions in the presence of pulsation (e.g. from the heart) are developed. Bessel functions are introduced as an aside. The concepts of shocks and solitary waves (solitons) are then …
