Apparent stresses in disturbed pulsatile flows
Journal of Biomechanics, 1988Traditional attempts at decomposing measured velocities into repeatable and random components are examined for a set of velocity data measured under pulsatile flow conditions distal to a 90% axisymmetric constriction. The Reynolds numbers, which are typical of those found in the human carotid artery, are such that transitional phenomena occur during ...

Dynamics of Pulsatile Blood Flow III
2015Solutions of fluid flow problems, to fully determine the dynamics of the fluid, including a mapping of the velocity field and of the relation between the prevailing pressure and flow fields, are possible only in the most simply constructed cases and mostly in the physical sciences.

Experimental Investigation of Pulsatile Flows in Tubes
Journal of Biomechanical Engineering, 1997Based on cam-piston-valve arrangement, a mechanical pulsatile flow generator is designed to investigate sinusoidal flow and other types of pulsatile flow in straight rigid tube. Measurement reveals the relation between pressure gradient and flow rate.

Pulsatile driving of the helical flow pump
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013The helical flow pump (HFP) is newly developed blood pomp for total artificial heart (TAH). HFP can work with lower rotational speed than axial and centrifugal blood pump. It can be seen reasonable feature to generate pulsatile flow because high response performance can be realized.

Flow velocity measurements for pulsatile flow
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1988The inherent sensitivity of magnetic resonance imaging to motion makes it particularly well-suited as a noninvasive flow measurement modality. A pulse sequence which labels moving material by subjecting it to a pulse that inverts the longitudinal magnetization is discussed.

Effects of transients on pulsatile flow in arteries
Biorheology, 2011Analytical solutions to the model problem of unsteady Newtonian fluid flow in straight, elastic-walled vessels can provide: theoretical insights into the flow of blood in arteries; a theoretical basis for clinical measurements in diagnoses of arterial flow rates; and guidance for boundary conditions in numerical simulations of flow in finite ...
