Abdominal aneurysms are abnormal localized dilations of an artery that can be lethal. The primary objective is to use the finite volume approach to study biomechanical parameters for 3D generic aneurysms. This work uses computational fluid dynamics to analyze the blood flow behaviour in a diseased abdominal aortic aneurysm with modeled generic geometry. An observation made from the study showed a ...Show More
Aneurysmal disease, which results in vessel expansion and, in some instances, rupture, is fatal. This work illustrates the steady-state analysis of generic aneurysm models with smooth expansion and contraction with a bulge ratio of D/d ranging from 1.5 to 2.5. These designs were simulated using Reynolds number 1170. This study aims to develop a framework to investigate the various 3D turbulence, n...Show More
The number of patients suffering from kidney related issues are exponentially rising each year. According to health organizations, kidney patients are more in count than the diabetic patients which make it more alarming. Hemodialysis is the treatment for patients with failed kidney, till a normal kidney is at hand for transplant. A high flux crimped membrane is designed and simulated. In this pape...Show More
High flux hemodialyzer membranes of different average porosities were modelled. Diffusion and convection property of a toxin molecule through the membrane was observed through simulation using Finite element method. In this study, a porous membrane having a porosity of 0.15 was compared to that of 0.3 membrane porosity. Different synthetic polymers having such porosities were thus considered for t...Show More
A high flux membrane is modelled for hemodialyzers. The function of high flux membrane is simulated to observe its role in overall toxin clearance and retaining necessary solutes. In this study, hemodialyzer with a single membrane and multiple membranes are modelled using Finite element method. Toxin clearance is observed by varying different geometric parameters of the hollow fiber and velocity p...Show More
