PULSATILE 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 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 کاملA pulsatile developing flow in a bend
Low frequency pulsatile flow of an incompressible viscous fluid has been numerically investigated in a rigid 90° bend of circular cross-section, using the finite-volume method. The governing parameters are as follows : amplitude ratio of 1.25, Womersley
متن کاملPulsatile flow in a model carotid bifurcation.
Pulsatile flow in an in vitro model of the human carotid bifurcation was studied by flow visualization using hydrogen bubble techniques. A glass model was constructed after determining an average geometry from 57 biplanar angiograms of 22 subjects ranging from 34 to 77 years of age. The flow pulse used was a half-sine wave superimposed upon a mean flow. Maximum and minimum values of the instant...
متن کاملPulsatile 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...
