  • Descrição: The impact of the flow of nanoparticles in nanofluids (NFs) across a vertical area is considerable, and its request in engineering, medical sciences, pharmaceutical, and food industries is vast and widely published. Nevertheless, the comparative analysis of alumina (Al 2 O 3 ) nanoparticles through cupric (CuO) nanoparticles over a rapid progressive Riga plate remains unidentified. Hence, this report scrutinizes water-based Al 2 O 3 and CuO nanoparticles via an exponentially accelerated Riga plate. NFs containing aluminium oxide and copper (II) oxide nanoparticles are considered. The Laplace transform technique is utilized to solve the PDEs guiding the flow. The range of the nanoparticle volume fraction is 1–4%, the buoyancy forces convection ranging from 5 to 20, and the modified Hartmann number ranging from 1 to 6. The impact of a variety of factors on Nusselt number, skin friction coefficient, temperature, and velocity profiles is examined and reported in tabular and graphical form. The upsurge of radiative impact and modified Hartmann number improves CuO NF compared to Al 2 O 3 NF due to Lorentz force and since cupric is a better heat conductor. At the same time, heat absorption and reactive species favour a slight decline in Al 2 O 3 NF than CuO NF in the thermal and velocity fields. The higher density of cupric NF is improved by rising nanoparticle volume fraction over Al 2 O 3 NF through a decline in velocity distribution.
