Thermal radiation effects on Bingham–Papanastasiou tetra-hybrid nanofluid dynamics in a porous diseased artery with electro-osmotic flow and permeability

The increasing prevalence of cardiovascular disorders necessitates advanced computational approaches to investigate blood flow dynamics in stenotic arteries. This examination studies the combined influence of electro-osmotic forces and nanoparticles on the blood flowing via a tapered, porous-saturated artery featuring stenosis, with the influences of magnetized fields and body acceleration. A key innovation lies in the novel integration of tetra-hybrid nanoparticles (Tetra-HNFs) with the Bingham-Papanastasiou rheological framework to simulate the non-Newtonian performance of blood. This extends the conventional Tiwari and Das tetra-hybrid nanofluid framework to accommodate the tetra-HNF case, incorporating various shapes of nanoparticles for detailed analysis. The electrical phenomena induced by the applied electric field are described using the Poisson-Boltzmann equation, linearizing via the Debye-Hückel approximation because of the assumption of low zeta potential at the arterial walls. This results in a closed-form solution for the electric potential. The arterial vessel displays the penetrability impact, with an outside magnetized force used radially to the flowing. The mild stenosis approximation is applied to simplify the governing equations. The study employs a finite difference methodology to numerically resolve the governing equations, analyzing the effects of electro-osmotic forces, nanoparticle configurations, magnetic fields, and body acceleration on key hemodynamic factors. The results presented graphically highlight the impact on velocity profiles, temperature outline, surface shearing stress, flowing rate, and confrontation. This exploration runs new perceptions into the interaction of electro-osmosis, nanoparticle dynamics, and non-Newtonian blood behavior in complex arterial geometries. By leveraging computational biomedical simulations, the study contributes to the advancement of diagnostic and therapeutic strategies for cardiovascular conditions, paving the way for improved clinical outcomes. • Tetra-hybrid nanofluid with the Bingham-Papanastasiou model to simulate blood in stenotic artery is examined. • Electro-osmotic forces using the Poisson-Boltzmann equation and Debye-Hückel approximation are analyzed. • Nanoparticles effect, magnetic field, body acceleration, temperature, and surface shear stress are investigated. • Mild stenosis approximation is exploited to simplify regulating equations, then solved by finite difference method. • Hemodynamic insights to enhance advanced diagnostic and therapeutic strategies for cardiovascular diseases are provided.
