Abstract Numerous studies have suggested that medical image derived computational mechanics models could be developed to reduce mortality and morbidity due cardiovascular diseases by allowing for patient‐specific surgical planning customized device design. In this work, we present a novel framework designing prosthetic heart valves using parametric design platform immersogeometric fluid–structure interaction (FSI) analysis. We parameterize the leaflet geometry several key parameters. This...
This paper aims to examine the effects of variations in vocal fold (VF) morphological features associated with gender on glottal aerodynamics and tissue deformation. Nine three-dimensional geometries VFs larynx are created various VF lengths, thicknesses, depths perform a parametric analysis according gender-related geometrical parameters. The computational model is incorporated fluid–structure interaction methodology by adopting transient Navier–Stokes equations airflow through considering...
The objective of this paper is to analyze the association intraluminal thrombus (ILT) presence and morphology with oxygen transport in abdominal aortic aneurysms (AAA) local hypoxia. biomechanical role ILT layer evolution aneurysm still not fully understood. has been shown create an inflammatory environment by reducing flux arterial wall therefore decreasing its strength. It also hypothesized that geometry may further affect AAA rupture. However, no previous research attempted explore effect...
Determination of abdominal aortic aneurysm (AAA) rupture risk involves the accurate prediction mechanical stresses acting on arterial tissue, as well wall strength which has a correlation with oxygen supply within aneurysmal wall. Our laboratory previously reported significance an intraluminal thrombus (ILT) presence and morphology localized deprivation by assuming uniform consistency ILT. The aim this work is to investigate effects ILT structural composition flow adopting multilayered...
This paper reports on modelling and simulation of the coupled mass momentum transport through arterial lumen porous wall an abdominal aortic aneurysm (AAA). The effect structure intramural flow, which is usually neglected, essential to quantify oxygen concentration in aneurysmal will be addressed this work via a novel fluid–porous structure–mass model for AAA. computational solver provides prediction filtration velocity artery further simulations are used investigate relation between...
The objective of this work is modeling the interaction between pulsatile blood flow and arterial walls. We model in arteries as an incompressible viscous fluid with Newtonian rheology, confined by a poroelastic wall modeled Biot equations. propose loosely coupled solution strategy fluid-structure problem, which allows solving Navier-Stokes equations separately. In way, we uncouple original problem into two parts defined on separate subregions. At end, partitioned scheme exploited...
The mechanisms of abdominal aortic aneurysm (AAA) formation and rupture are controversial in the literature. While intraluminal thrombus (ILT) plays a crucial role reducing oxygen flux to tissue therefore decreasing wall strength, other physiological parameters such as vasa vasorum (VV) flow its consumption contribute altered oxygenation responses arterial well. goal this research is analyse importance aforementioned on delivery aneurysmal patient-specific AAA. Numerical simulations coupled...
Human phonation involves the flow-induced vibrations of vocal folds (VFs) that result from interaction with airflow through larynx. Most voice dysfunctions correspond fluid–structure (FSI) features as well local changes in perfusion within VF tissue. This study aims to develop a multiphysics computational framework simulate interstitial fluid flow dynamics vibrating VFs using biphasic description tissue and FSI methodology. The integration permeable model presents novel approach capture...
