Blood Flow

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

Applications of Integration to Find Blood Flow

Applications of Integration to Find Blood Flow

Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...

Development of Blood Vessels

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Autoregulation of Blood Flow

Autoregulation of Blood Flow

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.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation.

Anatomy of Blood Vessels

Anatomy of Blood Vessels

The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta, have...

Background:

One-dimensional blood flow models are crucial for simulating pressure and flow waveforms in human arterial circulation.
Existing models often face computational time limitations, hindering complex simulations.

Purpose of the Study:

To develop and evaluate novel algorithms for accelerating one-dimensional blood flow models using graphics processing units (GPUs).
To compare the performance of new hybrid CPU-GPU and GPU-only algorithms against existing single-threaded and multi-threaded CPU implementations.

Main Methods:

Development of a parallel hybrid CPU-GPU algorithm with compact copy operations (PHCGCC) and a parallel GPU only (PGO) algorithm.
Evaluation of second-order numerical schemes (Lax-Wendroff, Taylor series) for model solutions.
Testing with physiologically relevant non-periodic (Windkessel) and periodic boundary conditions (structured tree), and elastic/viscoelastic wall laws.

Main Results:

Both PHCGCC and PGO algorithms demonstrated significant improvements in execution time.
Speed-up factors ranged from 5.26 to 8.10× over single-threaded CPU and 1.84 to 4.02× over multi-threaded CPU implementations.
PHCGCC excelled with elastic wall laws (non-periodic BC) and viscoelastic laws, while PGO was optimal for elastic laws with periodic BC.

Conclusions:

The proposed GPU-accelerated algorithms, PHCGCC and PGO, offer substantial speed-ups for one-dimensional blood flow simulations.
Algorithm performance is dependent on specific boundary conditions and wall law properties.
These advancements enable faster and more efficient computational modeling of arterial hemodynamics.
