Elliptic cross sections in blood flow regulation [PDF]
arXiv, 2023 Arterial deformations arise in blood flow when surrounding tissue invades the space available for a blood vessel to maintain its circular cross section, the most immediate effects being a reduction in blood flow and redistribution of shear stress. Here we consider deformations from circular to elliptic cross sections. Solution of this problem in steady

Deformable Registration of MRA Images with 4D Flow Images to Facilitate Accurate Estimation of Flow Properties within Blood Vessels [PDF]
arXiv, 2023 Patients with congenital and acquired heart conditions often undergo studies using Magnetic Resonance Angiography (MRA) images and time-resolved four-dimensional phase-contrast magnetic resonance (4D Flow) images to noninvasively estimate blood flow properties such as flux, wall shear stress and vorticity.

Patterns Formation in Drying Drops of Blood [PDF]
, 2010 The drying of a drop of human blood exhibits coupled physical mechanisms, such as Marangoni flow, evaporation and wettability. The final stage of a whole blood drop evaporation reveals regular patterns with a good reproducibility for a healthy person.

Hemodynamical Behavior Analysis of Anemic, Diabetic, and Healthy Blood Flow in the Carotid Artery [PDF]
The influence of blood rheology on hemodynamic parameters is investigated using Computational Fluid Dynamics on blood flow through the human carotid artery. We performed three-dimensional modeling and simulation to study blood flow through the carotid artery, which is divided into internal and exterior parts with a decreased radius.

Autonomous Robotic Suction to Clear the Surgical Field for Hemostasis using Image-based Blood Flow Detection [PDF]
arXiv, 2020 Autonomous robotic surgery has seen significant progression over the last decade with the aims of reducing surgeon fatigue, improving procedural consistency, and perhaps one day take over surgery itself. However, automation has not been applied to the critical surgical task of controlling tissue and blood vessel bleeding--known as hemostasis.

Visual Exploration of Simulated and Measured Blood Flow [PDF]
arXiv, 2012 Morphology of cardiovascular tissue is influenced by the unsteady behavior of the blood flow and vice versa. Therefore, the pathogenesis of several cardiovascular diseases is directly affected by the blood-flow dynamics. Understanding flow behavior is of vital importance to understand the cardiovascular system and potentially harbors a considerable ...

Towards a Mathematical Model for the Solidification and Rupture of Blood in Stenosed Arteries [PDF]
arXiv, 2020 In this paper, we present a mathematical and numerical model for blood solidification and its rupture in stenosed arteries. The interaction between the blood flow and an existing stenosis in the arterial wall is modeled as a three dimensional fluid-structure interaction problem.

A model for red blood cells in simulations of large-scale blood flows [PDF]
arXiv, 2011 Red blood cells (RBCs) are an essential component of blood. A method to include the particulate nature of blood is introduced here with the goal of studying circulation in large-scale realistic vessels. The method uses a combination of the Lattice Boltzmann method (LBM) to account for the plasma motion, and a modified Molecular Dynamics scheme for the ...

Comparative Mathematical Study of Blood Flow Through Stenotic and Aneurysmatic Artery with the Presence and Absence of Blood clots [PDF]
arXiv, 2020 Numerical predictions of blood flow and hemodynamic properties through a stenotic and aneurysmal rigid artery are studied in the presence of blood clot at constricted area. Finite element method has been used to solve the steady partial differential equations of continuity, momentum, Oldroyd-B and bioheat transport in two dimensional cartesian ...
