Pulsatile Blood Flow in a Pipe
ÐThe unsteady ̄ow of blood in a straight, long, rigid pipe, driven by an oscillatory pressure gradient is studied. Three dierent non±newtonian models for blood are considered and compared. One of them turns out to oer the best ®t of experimental data, when the rheological parameters are suitably ®xed. Numerical results are obtained by a spectral collocation method in space and the implicit tr...
متن کاملPulsatile Blood Flow
In addition to many overly restrictive simplifications of this type, the text offers some extraordinary and equally arresting therapeutic suggestions. In 1964, it is intriguing to discover that relief in pericarditis "is often obtained from the application of four or five leeches over the praecordium," that extract of ox gall may help the symptoms of acute hepatitis, and that "Kaolin poultices ...
متن کاملPULSATILE MOTION OF BLOOD IN A CIRCULAR TUBE OF VARYING CROSS-SECTION WITH SLIP FLOW
Pulsatile motion of blood in a circular tube of varying cross-section has been developed by considering slip flow at the tube wall and the blood to be a non- Newtonian biviscous incompressible fluid. The tube wall is supposed to be permeable and the fluid exchange across the wall is accounted for by prescribing the normal velocity of the fluid at the tube wall. The tangential velocity of the fl...
متن کاملTurbulent Pulsatile Pipe Flow with Multiple Modes of Oscillation
This study numerically investigates turbulent pipe flow driven by a pulsating pressure gradient. While studies of laminar and turbulent pulsatile pipe flow with a single mode of oscillating pressure gradient have been carried out extensively, there is scarce literature on pulsating pressure gradients with multiple temporal Fourier modes. In many real-life engineering applications, for example, ...
متن کاملPulsatile Ocular Blood Flow in Healthy Koreans
PURPOSE To determine the normal reference range of pulsatile ocular blood flow (POBF) values in healthy Korean subjects and to find out the factors that may affect them. METHODS A total of 280 eyes of 280 normal subjects were included in this study. Best corrected visual acuity (BCVA), intraocular pressure (IOP), axial length, POBF, systemic blood pressure, and pulse rate were measured. The m...
