SUMMARY The importance of the endothelium in the local regulation of blood flow is reflected by its influence on vascular tone by means of vasodilatory responses to many physiological stimuli. Regulatory pathways are affected by mass transport and wa

In this paper, a local time stepping approach is proposed for incompressible flow calculations using a quasi-implicit time discretization. Since the non-linear convection term is treated explicitly by this discretization, the convective part of the t

SUMMARY In this paper, a robust and semi-automatic modelling pipeline for blood flow through subject-specific arterial geometries is presented. The framework developed consists of image segmentation, domain discretization (meshing) and fluid dynamics

Transient blood flow through a geometrically patient-specific human aorta with a thoracic aortic aneurysm (TAA) is carried out. Special attention is given to the folded neck (kink) of the aneurysm found in the geometry studied. It is a common practic

In the present work, blood flow through a patient-specific carotid bifurcation is thoroughly analysed. A locally conservative Galerkin spatial discretization is applied along with an artificial compressibility and characteristic-based split scheme to

In this study, an improved and robust one-dimensional human arterial network model is presented. The one-dimensional blood flow equations are solved using the Taylor-locally conservative Galerkin finite element method. The model improvements are carr

PurposeThe purpose of this paper is to numerically study blood flow through a subject‐specific carotid artery with a moderately severe stenosis, also to thoroughly analyse the wall shear stress (WSS), oscillatory shear index (OSI) and WSS angular d

In this paper, the locally conservative Galerkin (LCG) method (Numer. Heat Transfer B Fundam. 2004; 46:357-370; Int. J. Numer. Methods Eng. 2007) has been extended to solve the incompressible Navier-Stokes equations. A new correction term is also inc
