Impact of competitive flow on wall shear stress in coronary surgery: computational fluid dynamics of a LIMA-LAD model [PDF]

open access: yes, 2010
Competitive flow from native coronary vessels is considered a major factor in the failure of coronary bypass grafts. However, the pathophysiological effects are not fully understood.

Numerical Investigation of the Vibration of a Circular Cylinder in Oscillatory Flow in Oblique Directions

open access: yesJournal of Marine Science and Engineering, 2022
The response of an elastically mounted circular cylinder vibrating in an oscillatory flow oblique to the flow direction is investigated. Simulations are conducted for vibration angles ranging from 0° to 90°, with 0° and 90° corresponding to the cases ...

Navier slip and suction/injection effects on oscillatory flow of nanofluid with fluid-particle interaction in a channel [PDF]

open access: yesE3S Web of Conferences, 2021
In this paper, the slip and porosity effects on the channel walls are studied for the oscillatory flow of heat-absorbing/generating dusty nanofluid flowing through a porous medium.

Particle Coherent Structures in Confined Oscillatory Switching Centrifugation

open access: yesCrystals, 2021
A small spherical rigid particle in a cylindrical cavity is considered. The harmonic rotation of the cavity wall drives the background flow characterized by the Strouhal number Str, assumed as the first parameter of our investigation.

Slow oscillatory Stokes flow [PDF]

open access: yesQuarterly of Applied Mathematics, 1997
Two transient problems in slow viscous flow are considered where the corresponding steady-state behaviour leads to the paradoxical results of Stokes and Jeffery. First, the oscillatory flow past a circular cylinder is investigated when the frequency λ \lambda tends to zero, where an outer domain of size O

Faxén's law for arbitrary oscillatory Stokes flow past a porous sphere

open access: yesArchives of Mechanics, 2012
The present article deals with the study of the hydrodynamics of a porous sphere in an oscillatory viscous flow of an incompressible Newtonian fluid. Unsteady Stokes equations are used for the flow outside the porous sphere and Darcy's equation is used ...

Oscillatory Flow Near a Stagnation Point [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2003
The authors consider an unsteady version of classical Hiemenz solution describing incompressible two-dimensional stagnation point flow at a solid wall, examining particularly the response close to the wall when the solution at infinity is modulated in time by a periodic factor of specified amplitude and frequency for arbitrary values of these ...

Numerical simulation of vortex-induced vibration of a 2D cylinder in oscillatory flow

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives] In the actual oil and gas exploitation,the combined actions of wind, waves and currents may cause the offshore platform to oscillate periodically,and then the relative oscillatory flow is generated between risers connected to the platform ...

Valve Endothelial Cell Exposure to High Levels of Flow Oscillations Exacerbates Valve Interstitial Cell Calcification

open access: yesBioengineering, 2022
The aortic valve facilitates unidirectional blood flow to the systemic circulation between the left cardiac ventricle and the aorta. The valve’s biomechanical function relies on thin leaflets to adequately open and close over the cardiac cycle.
