Nanoparticles' Effect on Blood Flow

What is it about?

Nanoparticles in blood: Tiny particles (like metal or drug-carrying nanoparticles) are mixed into blood, which can change its flow and heat behavior. Arterial porous vessel: The blood vessel is treated as a “porous” surface, meaning it allows some fluid flow through its walls—like modeling permeability of the arterial wall. Stretching vessel surface: The vessel wall is assumed to be stretching, which affects how blood flows near it. Magnetohydrodynamics (MHD): A magnetic field is applied perpendicular to the blood flow, which can slow it down due to Lorentz forces. Thermal radiation and heat effects: Heat is generated or absorbed in the blood, and thermal radiation (heat transfer through emission) is considered. Chemical reaction: The nanoparticles may undergo reactions that change their concentration in blood over time. Purpose: To understand how all these factors—nanoparticles, magnetic field, heat, and chemical reactions—affect blood velocity, temperature, and nanoparticle concentration. This has potential applications in targeted drug delivery and biomedical engineering, where controlling blood flow and heat transfer can improve treatment effectiveness.

Why is it important?

Targeted drug delivery: Nanoparticles can carry drugs directly to specific parts of the body. Understanding how they move in blood under magnetic fields, heat, or chemical reactions helps design more effective therapies with fewer side effects. Magnetic field control: Applying magnetic fields can slow down or redirect blood flow carrying nanoparticles. This is useful for guiding drugs to tumors or blocked arteries. Heat management: Blood flow is affected by heat (from metabolism, therapy, or external sources). Modeling thermal radiation and heat generation/absorption helps predict how temperature affects nanoparticle distribution and flow stability. Chemical reactions of nanoparticles: Some nanoparticles may react with their environment. Knowing how this affects concentration ensures consistent dosing and therapeutic effect. Arterial health modeling: Porous artery walls and stretching behavior simulate real physiological conditions, which helps researchers design treatments that work in realistic blood vessels.
