Heat and mass transfer analysis of radiative and chemical reactive effects on MHD nanofluid over an infinite moving vertical plate

A comparative study of nanofluid (Cu-H2O) and pure fluid (water) is investigated over a moving upright plate surrounded by a porous surface. The novelty of the study includes the unsteady laminar MHD natural transmission flow of an incompressible fluid, to get thermal conductivity of nanofluid is more than pure fluid. The chemical reaction of this nanofluid with respect to radiation absorption is observed by considering the nano particles to attain thermal equilibrium. The present work is validated with the previously published work. The upright plate travels with a constant velocity u0, and the temperature and concentration are considered to be period harmonically independent with a constant mean at the plate. The most excellent appropriate solution to the oscillatory pattern of boundary layer equations for the governing flow is computed utilizing the Perturbation Technique. The impacts of factors on velocity, temperature, and concentration are visually depicted and thoroughly elucidated. The fluid features in the boundary layer regime are explored visually and qualitatively. This enhancement is notably significant for copper nanoparticles.

Automated summary

This study investigates the performance of nanofluid (Cu-H2O) and pure fluid (water) on a porous surface over a moving upright plate using the Perturbation Technique. The results show that the thermal conductivity of Cu-H2O nanofluid is higher than that of pure water, which is attributed to the chemical reaction of nanoparticles enhancing radiation absorption. The experimental findings are validated with previous studies and the impacts of factors are thoroughly discussed and explained.
