Newtonian and Non-Newtonian Blood Flow Simulation after Arterial Stenosis- Steady State and Pulsatile Approaches
Arterial stenosis, for example Atherosclerosis, is one of the most serious forms of arterial disease in the formation of which hemodynamic factors play a significant role. In the present study, a 3-D rigid carotid artery with axisymmetric stenosis with 75% reduction in cross-sectional area is considered. Laminar blood flow is assumed to have both Newtonian and non-Newtonian behavior (generalize...
متن کاملNumerical Study of Hemodynamic Wall Parameters on Pulsatile Flow through Arterial Stenosis
In this paper hemodynamic wall parameters which play an important role to diagnose arterial disease were studied and compared for three different rheology models (Newtonian, Power law and Quemada). Also because of the pulsatile behavior of blood flow the results were obtained for three Womersley numbers which represent the frequencies of the applied pulses. Results show that Quemada model alway...
متن کاملStudy of Pulsatile Non-Newtonian Blood Flow Through Abdominal Aorta and Renal Arteries Incorporating Fluid- Structure Interaction
Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...
متن کاملPulmonary capillaries are recruited during pulsatile flow.
Capillaries recruit when pulmonary arterial pressure rises. The duration of increased pressure imposed in such experiments is usually on the order of minutes, although recent work shows that the recruitment response can occur in <4 s. In the present study, we investigate whether the brief pressure rise during cardiac systole can also cause recruitment and whether the recruitment is maintained d...
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 ...
