Modeling Blood Flow in a Stenotic Artery Using Maxwell Au-Bloood Nanofluid: Insights into Hemodynamics and Nanoparticle Dispersion

This study uses the Maxwell nanofluid framework to introduce a novel method for simulating blood flow in a stenotic artery. The hyperbolic tangent sigmoid function is incorporated into the suggested model to describe the intricate rheological behavior of the blood-nanoparticle solution. The model offers insights into the flow characteristics and hemodynamic parameters within the stenotic artery by taking into account the stenosis-induced geometrical abnormalities and the nanoparticle dispersion. In order to effectively characterize the shear-thinning behavior of the nanofluid and produce more precise forecasts of flow patterns and pressure drop across the stenosis, the hyperbolic tangent sigmoid function is a crucial component. The results of this work advance our knowledge of the hemodynamics of blood-nanoparticle mixes in stenotic arteries, perhaps paving the way for more effective cardiovascular disease diagnostic and treatment approaches. This work introduces a novel model strengthened by the hyperbolic tangent sigmoid function, which is used to mimic blood flow in a stenotic artery using the Maxwell nanofluid framework. The blood-nanoparticle solution's complex rheological behaviors are shown by the results, which also demonstrate surprising temperature amplification using gold nanoparticles. A primary emphasis that results in an enlarged temperature field is the interaction between viscosity and temperature. Our knowledge of hemodynamics in stenotic arteries is improved by these findings, which may have implications for cardiovascular diagnosis and therapy strategies.
