The Investigation of Terminal Segment Effect on Blood Pressure Propagation Patterns in Cardiovascular System Models

open access: yesCommunications, 2011
The electro-mechanical analogy method is used for the simulation of blood flow in blood vessels. Particularly the subject of this paper is the investigation of the influence of terminal segment topology on the blood pressure propagation patterns.

Modeling a 3-D multiscale blood-flow and heat-transfer framework for realistic vascular systems

open access: yesScientific Reports, 2022
Modeling of biological domains and simulation of biophysical processes occurring in them can help inform medical procedures. However, when considering complex domains such as large regions of the human body, the complexities of blood vessel branching and

Numerical Modelling of Erythrocyte Sticking Mechanics

open access: yesApplied Sciences, 2022
The mechanics of thrombus formation includes the interaction of platelets, fibrin, and erythrocytes. The interaction was analyzed as the erythrocyte approaches the activated platelet and fibrin thrombus formation.

Large–Eddy simulation of pulsatile blood flow [PDF]

open access: yesMedical Engineering & Physics, 2008
Large-Eddy simulation (LES) is performed to study pulsatile blood flow through a 3D model of arterial stenosis. The model is chosen as a simple channel with a biological type stenosis formed on the top wall. A sinusoidal non-additive type pulsation is assumed at the inlet of the model to generate time dependent oscillating flow in the channel and the ...

Spectral models for 1D blood flow simulations [PDF]

open access: yes2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010
In this paper we introduce a new theoretical formulation for the description of the blood flow in the circulatory system. Starting from a linearized version of the Navier-Stokes equations, the Green's function of the propagation problem is computed in a rational form.

Modeling of intracranial vessels and Simulation of cerebral blood flow [PDF]

open access: yesE3S Web of Conferences, 2020
The stable regulation of cerebral blood flow plays an important role in the normal operation of brain function. The disturbance of cerebral blood flow automatic regulation will lead to brain injury and lead to cerebrovascular disease. Therefore, it is of

Blood Flow Simulation System with Interaction between Blood Flow and Blood Vessel Wall using Image Based Cartesian Grid

open access: yesJournal of Biomechanical Science and Engineering, 2008
For the simulation of the fluid-structure interaction (FSI) between the blood flow and blood vessel walls, we have examined the voxel-based FSI method. This method uses a Cartesian grid, called voxel, made from medical images. Further, we have tested the

Numerical Simulation of Blood Flow in a Blood Vessel

open access: yesJournal of Computational and Engineering Mathematics
Summary: The paper proposes a finite-difference method for solving a boundary value problem for a hyperbolic equation describing the movement of blood in a blood vessel. The stability conditions of the method are given, and numerical results are presented.
