Pulsatile flow between two coaxial porous cylinders with slip on inner cylinder for large frequency of pulsation.
(2011-10-13)
The unsteady component of axial flow of an incompressible fluid in the region lying between the annular spaces of two coaxial cylinders has been investigated. The outer cylinder is assumed to possess uniform permeability ...
Pulsatile flow between two coaxial porous cylinders with slip on inner cylinder.
(2011-10-13)
A fully developed, axisymmetric, pulsatile motion of an incompressible Newtonian fluid,under the action of an oscillatory pressure gradient, has been considered in this work. The fl ow is assumed to take place in the ...
Importancia ecológica e hidráulica del Régimen pulsátil del río Sinú - departamento de Córdoba
(Bogotá : Universidad de Ciencias Aplicadas y Ambientales, 2001, 2001-03)
The knowledge of the ecological and hydraulic processes of the rivers is in a development State, more yet in tropical rivers. Some investigations in this topic question the concept of the operation of the rivers as closed ...
Blood flow dynamics and arterial wall interaction in a saccular aneurysm model of the basilar artery
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-08)
Blood flow dynamics under physiologically realistic pulsatile conditions plays an important role in the growth, rupture and surgical treatment of intracranial aneurysms. This paper describes the flow dynamics and arterial ...
Blood flow dynamics in saccular aneurysm models of the basilar artery
(ASME-AMER SOC MECHANICAL ENG, 2006-08)
Blood flow dynamics under physiologically realistic pulsatile conditions plays an important role in the growth, rupture, and surgical treatment of intracranial aneurysms. The temporal and spatial variations of wall pressure ...
Pulsating Flow of an Ostwald-De Waele Fluid between Parallel Plates
(MDPI, 2020)
The flow between two parallel plates driven by a pulsatile pressure gradient was studied analytically with a second-order velocity expansion. The resulting velocity distribution was compared with a numerical solution of ...

Non-Newtonian blood flow dynamics in a right internal carotid artery with a saccular aneurysm
(JOHN WILEY & SONS, 2006-02)
Flow dynamics, plays an important role in the pathogenesis and treatment of cerebral aneurysms. The temporal and spatial variations of wall shear stress in the aneurysm are hypothesized to be correlated with its growth and ...
A review on computational fluid dynamics modelling in human thoracic aorta
(Universidad Autónoma de Occidente, 2013-06)
It has long been recognized that the forces and stresses produced by the blood flow on the walls of the cardiovascular system are central to the development of different cardiovascular diseases. ...
