Chemical reaction and inclined magnetic field effects on tri-hybrid Carreau nanofluid slip flow of blood past a porous inclined stenosed artery with viscous dissipation

Abstract A steady magnetohydrodynamic (MHD) slip flow of blood carrying tri-hybrid nanoparticles via a porous inclined stenosed artery has been considered. Non-Newtonian blood rheology has been incorporated using the Carreau fluid model. Darcy-Forchheimer model has been utilized to predict the fluid flow in the porous medium. An external inclined magnetic field has been applied. Consequences of viscous dissipation, Ohmic heating, and chemical reaction have been studied. Copper (Cu), iron oxide (Fe 3 O 4 ), and silicon oxide (SiO 2 ) have been considered as nanoparticles. Assumption of mild stenosis has been used to simplify the system of governing equations. Homotopy Perturbation Method (HPM) has been employed to find the series solution for axial velocity, temperature, and concentration. Total entropy generation has been calculated to scrutinize the irreversibility of the system. Proposal has been evaluated based on the axial velocity of flow, thermal, concentration, and entropy profiles of mono, hybrid, and tri-hybrid nanofluids concerning various controlling parameters. Blood flow patterns have been noted by plotting streamlines against various controlling parameters. It has been observed that axial velocity, concentration, and entropy profiles of tri-hybrid nanofluid subdue the other two whereas thermal profiles follow the opposite trend. Viscous dissipation improves the heat transfer by 17% and chemical reaction improves the mass distribution by 8%. Flow disturbance can be minimized by increasing the power-law index number and velocity slip parameter. Accuracy of the outcomes presented in this study has been compared with the previously published data. This rheological model is useful for targeted and controlled drug delivery.
