The flow is defined as an unsteady, incompressible, laminar Newtonian fluid, with blood exhibiting Newtonian properties at elevated shear rates. An algorithm for mass, velocity, and energy, as well as a fine element\u2010sized mesh, was developed using the computational fluid dynamics (CFD) technique based on the finite element method. Here, systematic observation of the effect of varying nanoparticle volume fractions (\n                    <jats:italic>\u03d5<\/jats:italic>\n                    = 3\n                    <jats:italic>%<\/jats:italic>\n                    , 9\n                    <jats:italic>%<\/jats:italic>\n                    , 15\n                    <jats:italic>%<\/jats:italic>\n                    ) and Reynolds numbers (Re) on the resulting flow velocity profiles. Although maximal velocity is geometrically concentrated at the stenosis throat, the critical determining factor of patient danger is the concentration\u2010dependent change in fluid viscosity. Increasing\n                    <jats:italic>\u03d5<\/jats:italic>\n                    raises effective viscosity (Brinkman model), progressively flattening the velocity profile into a blunt, plug\u2010like regime; paradoxically, this near\u2010uniform plug, lacking the gradual wall\u2010to\u2010core velocity gradient of a parabolic profile, is unable to resist the adverse pressure gradient at the abrupt poststenotic expansion, causing simultaneous cross\u2010sectional deceleration and abrupt flow separation that sustains larger, more energetic recirculation zones than those observed at lower\n                    <jats:italic>\u03d5<\/jats:italic>\n                    . This disturbed distal flow that generates large and persistent recirculation zones downstream of the stenosis, which are associated with increased thrombotic risk due to disturbed flow patterns. Conversely, the increase in\n                    <jats:italic>\u03d5<\/jats:italic>\n                    drastically increases thermal conductivity, making the heat transfer process nearly independent of flow speed, that a key insight for forthcoming contained thermal therapies. Eventually, this research delivers a mechanistic link between fluid rheology, flow instability, and thrombotic risk, signifying that therapeutic strategies need to prioritize the management of fluid viscosity to stabilize poststenotic flow fields and mitigate associated cardiovascular complications. This work is the first effort to evaluate the impact of trihybrid nanofluid rheology on the exacerbation of poststenotic flow instability at clinically relevant Re. This reveals that a critical higher nanoparticle loading (\n                    <jats:italic>\u03d5<\/jats:italic>\n                    ) improves thermal conductivity. The present findings have direct significance for biomedical applications like targeted photothermal therapy (PTT), antimicrobial vascular intervention, and nanoparticle\u2010mediated drug delivery in cardiovascular disease management.
