Published: Jan. 21, 2025

This study examines heat transfer and nanofluid-enhanced blood flow behaviour in stenotic arteries under inflammatory conditions, addressing critical challenges cardiovascular health. The blood, treated as a Newtonian fluid, is augmented with gold nanoparticles to improve thermal conductivity support drug delivery applications. A hybrid methodology combining finite element method (FEM) for numerical modelling artificial neural networks (ANN) stability prediction provides robust analytical framework. Parametric analysis reveals that increasing stenosis severity (60% 80%) results 45% enhancement transfer, demonstrating the efficacy of nanoparticle integration. show size vortices decreases due position changing upper stenoses, whereas it rises peak. Higher volume fraction (ϕ) amplifies momentum diffusion, resulting larger vortices, while improved enhances transfer. Inflammation significantly affects patterns transport important implications treating disorders biological regression confirms close match between predicted target data, showcasing robustness FEM-ANN approach biofluid systems.

The current study deeply investigates nanofluid's heat and mass transport in a staggered-shaped enclosure with wavy walls. A nonhomogeneous mathematical model thermophoresis Brownian diffusion is considered our study. finite element method implemented to solve the set of governing equations. Impacts magnetic field (B0) its orientation (γ), undulation number (N), amplitude (A) nanoparticle types are examined for flow. Investigations show that most demoting trend obtained when inclination B0 either vertical or horizontal. It concluded mean Nusselt (Nuavg) Sherwood (Shavg) increasing functions Ra. When Ra changed from 103 107, Shavg value increased up six times. impacts wall shape as we increase A, Nuavg decreases while maximum can be flat boundary. For small N, an function. Shape optimization revealed there exists critical point between N after which it declines. further this changed. Some points have been calculated counted novel results.
