Hydrodynamic Characterization of an Arterial Flow Bioreactor
… investigate the response of endothelial cells to shear. The model interfaces a bioreactor with flow elements to compose a flow loop that reproduces arterial flow conditions within the bioreactor. High-resolution (8.6 microns) time-resolved (4 ms) velocity field measurements within the bioreactor …

Late Complications in the Descending Aorta Following Valve-Sparing Root Replacement (VSRR) in Marfan Syndrome (MFS) Patients: A Computational Analysis
… group exhibits lower time-averaged wall shear stress (TAWSS) and higher oscillatory shear index (OSI) and relative residence time (RRT) in the DA. Additionally, we observe a localized increase in TAWSS near the subclavian artery post-surgery in the “dissection” group, which is not …

Computational analysis on stent geometries in carotid artery
… based on parameters namely time averaged wall shear stress (TAWSS), time averaged wall shear stress gradient (TAWSSG), oscillatory shear index (OSI), relative residence time (RRT) and flow separation parameter (FSP). Meanwhile, Pictorial Selection Method was used to evaluate the best …

Studies of Stented Arteries and Left Ventricular Diastolic Dysfunction Using Experimental and Clinical Analysis with Data Augmentation
… examined <i>in-vitro</i> the changes in Wall Shear Stress (WSS) and Oscillatory Shear Index (OSI) caused by the implantation of coronary stents into the arteries of the heart using Particle Image Velocimetry. These experiments featured one-to-one scaling, commercial stents, and realistic flow …

Assessing the Near-Wall Hemodynamics in the Left Coronary Artery Using CFD
… evaluated. The parameters evaluated were: (i) Oscillatory Shear Index (OSI); which quantifies the extent in which the blood flow changes direction as it flows (ii) Time Average Wall Shear Stress (TAWSS); which quantifies the average shear stress experienced by the wall of the artery and (ii) …

Patient-specific computational haemodynamics in the arteriovenous fistula and aorta of a chronic kidney disease cohort
… are not easily measurable in-vivo, such as wall shear stress (WSS) and oscillatory shear index (OSI). CFD can therefore play a vital role in the pre-operative planning of AVFs, in addition to the postsurgical assessment. Despite the breadth of AVF research that has utilised CFD, there is still no …
