Hemodynamic and fluid flow analysis of a cerebral aneurysm: a CFD simulation

SN Applied Sciences, 2023
Highlights The presence of the aneurysms in the patient's vascular system leads presence of a flow vortex inside the bulge. The flow recirculation occurs due to separation at the rear edge of the aneurysm.

Steady streaming effect on the flow of a couple stress fluid through a constricted annulus

Archives of Mechanics, 2012
The oscillatory flow of an incompressible couple stress fluid through an annulus with mild constriction at the outer wall is considered. The mean pressure drops and the mean wall shear stress are calculated across the constricted region.

Stress overshoot in a simple yield stress fluid: an extensive study combining rheology and velocimetry

, 2011
We report a large amount of experimental data on the stress overshoot phenomenon which takes place during start-up shear flows in a simple yield stress fluid, namely a carbopol microgel.

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

Wall Shear Stress Distribution Inside Growing Cerebral Aneurysm [PDF]

American Journal of Neuroradiology, 2011
Hemodynamic stimulation has been suggested to affect the growth of cerebral aneurysms. The present study examined the effects of intra-aneurysmal hemodynamics on aneurysm growth.Velocity profiles were measured for 2 cases of AcomA aneurysms. Realistically shaped models of these aneurysms were constructed, based on CT angiograms.

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.
