Bioconvective blood flow of tetra composition nanofluids passing through a stenotic artery with Arrhenius energy

Abstract

The uncoupled forced blood flow in a stenosed artery using tetra-hybrid nanofluids is examined. The worked suspension is electrically conducting and containing oxytactic microorganisms. The direction of movements of the blood is perpendicular to the applied Lorentz force. During the formulation of the problem, several significant impacts are taken into account, for instance Joule heating, dissipation of viscosity, heat generation and activation energy proposed by Arrhenius. Four situations are considered based on the components of the nano-mixture, namely, mono-, Di-, Tri- and Tetra hybrid nanofluids. The method of the treatments starts with converting the governing system to dimensionless similar forms and solve numerically. The major results indicated that the rate of heat transport in case of the Tetra-hybrid nanofluids case is higher than those of the other cases. The rising in Weissenberg number enhances the values of the coefficient of skin friction.
