Description
Summary: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 nanoparticles 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. •The effects of reactions chemically and radiations thermally on the unsteady convective MHD flow is investigated.•The boundary layer equations governing the mass, momentum, energy and species concentration equations are solved•The plate is moving with a constant velocity U0, varied temperature, and varied concentration•The radiative heat flux is supposed to follow the Rosseland approximation.•There is a comparative analysis of the velocity and temperature profile heat transfer enhancement level
