Water-based hybrid nanofluid flow containing CNT nanoparticles over an extending surface with velocity slips, thermal convective, and zero-mass flux conditions

This study computationally examines the water-based hybrid nanofluid flow with the impacts of carbon nanotubes on an elongating surface. The flow is influenced by velocity slip constraints, zero-mass flux conditions, and thermal convection. Magnetic effects are applied to the flow system in the normal direction. The activation energy and chemical reactivity effects are used in the concentration equation. The modeled equations have been evaluated numerically through the bvp4c technique after conversion to dimensionless form through a similarity transformation approach. It has been discovered in this work that with expansion in magnetic and porosity factors, the velocities declined. Augmentation in the ratio factor has declined the primary flow velocity while supporting the secondary flow velocity. Thermal profiles have intensified with progression in the Brownian motion factor, thermal Biot number thermophoresis factor, and exponential heat source and radiation factors. Concentration distribution has escalated with the activation energy factor and has declined with an upsurge in Schmidt number and chemical reaction factors. The impact of an upsurge in the thermophoresis factor enhances the concentration distribution, while the upsurge in the Brownian motion factor exhibits a reducing impact on concentration distribution. To ensure the validation of this work, a comparative study is conducted in this work with a fine agreement among the current and established datasets.
