Abstract
This study is focused to investigate the blood flow pattern with motion of motile gyrotactic microorganisms. Since nanoparticles play an essential factor for enhancing delivery efficiency in vascular flow therefore physiochemical properties of these particles are considered in this examination. Prandtl fluid characteristics are instigated to discuss the blood flow rheology. Moreover, considerations of gyrotactic microbes with nanoparticles will exaggerate the thermal features of considered base fluid. The governing model output containing coupled nonlinear systems is evaluated by HPM technique. The features of flow defining parameters in an anisotropic stenotic region with motile microbes are inspected and presented through different illustrations. It is concluded from the governing nanofluid model that with addition of gyrotactic microbe’s hemodynamics factors of stenotic lesion are enhanced. Heat transfer rate phenomena depict opposite trends for nanoparticles key parameters involved in a governing problem.
