A comparative analysis of the blood-based hybrid nanofluid flow containing Cu and CuO nanoparticles over an exponentially extending surface

Abstract

This work investigates thermal enhancement for Casson magnetohydrodynamics (MHD) hybrid nanofluid flow on an exponentially elongating surface. The flow is influenced by thermal radiations, chemical reactivity, and heat source/sink. A magnetic field has been applied to the flow of fluid in a direction normal to the flow system. The thermal transportation has been controlled with the help of thermophoresis and Brownian motion effects. The leading equations have been converted to a set of dimensionless forms and have then been solved by using the bvp4c technique. It has been noticed in this work that, fluid velocities have declined with growth in porosity, magnetic, and Casson factors, and there is more reduction in velocity in the case of Cu + CuO/blood-based hybrid nanofluid as compared to blood flow or Cu/blood nanofluid profiles. Thermal distribution has augmented with an escalation in heat sink/source factor, Brownian motion, thermophoresis, magnetic and radiation factors as well as Eckert number. Concentration distribution has augmented with an upsurge in Brownian motion factor, Schmidt number, and chemical reactivity factor. Nusselt number has augmented with an escalation in magnetic, radiation, and heat sink/source factors as well as Eckert number. A comparative analysis has been carried out in this work with a fine agreement with previously established data. It has been established in this work that maximum heat is transformed in the case of Cu + CuO/blood hybrid nanofluid flow on an exponentially stretching sheet.
