Flow through a converging-diverging tube and its implications in occlusive vascular disease — I
TLDR
A mathematical model for a mild stenosis is established and an approximate solution for flow through a converging-diverging tube obtained, Velocity profiles, pressures, and wall shearing stresses along the tube are determined.About:

TL;DR: It is shown that three dimensionless parameters can be used to characterize the unsteady flow in a stenosis and the effect of unsteadiness is investigated experimentally using axisymmetric and nonsymmetric models.
Journal ArticleDOI
Fluid dynamics of coronary artery stenosis.
TL;DR: It is found that a relatively severe stenosis behaves essentially like an orifice and that a simple quasi-steady theory appears adequate to predict effects of a stenosis on coronary flow and that the theory appears promising for predicting effects of hemodynamic variables on a given stenotic lesion.
Journal ArticleDOI
Effects of stenosis on non-Newtonian flow of the blood in an artery.
TL;DR: It has been shown that the resistance of flow and the wall shear increase with the size of the stenosis but these increases are comparatively small due to non-Newtonian behaviour of the blood indicating the usefulness of its rheological character in the functioning of the diseased arterial circulation.
Journal ArticleDOI
Flow in arteries in the presence of stenosis.
TL;DR: Propagation of small amplitude harmonic waves, generated due to the flow of blood where the wave length is large compared to the radius of the arterial segment, is is considered in detail.

TL;DR: On severely damaged vessel wall, fibrin(ogen) and platelet deposition is maximal at the apex of the stenosis where shear rate is extremely high and parallel streamlines are deformed, and the pattern is not influenced by time.

TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.
