Summary
This study models blood flow through narrowed arteries (stenosis), a risk factor for COVID-19. Increased artery wall elasticity was found to improve blood flow, with findings comparable to existing research.
Area of Science:
- Biomedical Engineering
- Fluid Dynamics
- Cardiovascular Science
Background:
- Blood stenosis is a significant health risk and a symptom of COVID-19.
- Understanding blood flow dynamics in stenosed arteries is crucial for patient outcomes.
Purpose of the Study:
- To investigate blood flow in stenosed arteries considering blood clots and arterial wall elasticity.
- To compare the efficacy of the Rubinow & Keller and Mazumdar models for arterial elasticity.
Main Methods:
- Utilized the Herschel-Bulkley model for blood as a yield stress fluid.
- Employed Navier-Stokes equations for mathematical simulation.
- Incorporated Rubinow & Keller and Mazumdar models to simulate arterial wall elasticity.
Main Results:
- Demonstrated that increased arterial wall elasticity parameters facilitate blood flow through stenosis.
- Results for non-stenosed arteries align with established research by Vajravelu et al.
- Highlighted the importance of studying non-Newtonian fluid flow phenomena in cardiovascular contexts.
Conclusions:
- Arterial wall elasticity plays a key role in mitigating blood flow obstruction in stenosis.
- The Herschel-Bulkley model effectively simulates blood flow under these conditions.
- Further research into non-Newtonian fluid dynamics is warranted for cardiovascular health.

Hagen-Poiseuille flow describes a viscous fluid's steady, incompressible flow through a cylindrical tube with a constant radius R. This flow profile is often applied to understand fluid transport in narrow channels, such as capillaries. It serves as a foundational example of laminar flow. In this model, cylindrical coordinates (r,θ,z) are used to describe the radial (r), angular (θ), and axial (z) dimensions within the tube. For Hagen-Poiseuille flow, the velocity profile is...

Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.

For incompressible Newtonian fluids, where density remains constant, stresses show a linear relationship with the deformation rate, defined by normal and shear stresses. Normal stresses depend on the pressure exerted on the fluid and the rate of deformation in specific directions, which determines how fluid flows under varying pressures. Shear stresses, on the other hand, act tangentially across fluid layers. They explain how adjacent fluid layers slide relative to one another, connecting...

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

01:18Newtonian Fluid: Problem Solving
221
Newtonian fluids exhibit a constant viscosity, meaning their shear stress and shear strain rate are directly proportional. This property ensures a predictable and stable response to applied forces, maintaining a linear relationship between force and flow. Examples include water, air, and light oils, consistently demonstrating this proportional behavior regardless of external conditions.

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...
