Abstract
In current history, there has been a significant interest in contemporary nanostructures for nanoelectronic systems. These systems progressively employ dynamic media to boost efficiency. Inspired by its applications in engineering, The effect of radiation and heat sink on electromagnetic nanofluids flow past an exponentially accelerated Riga surface is studied analytically using the Laplace transform technique. The base fluid is water, and three selected nanoparticles are used: Copper, Titanium dioxide, and Aluminium oxide. The porous medium is taken into account, as well as the validity of the Boussinesq approximation. The influence of modified Hartmann number, heat absorption, Grashof number, and thermal radiation parameter on nanofluid velocity and temperature profiles is depicted graphically and discussed. The shear stress and Nusselt number are determined, and outcomes are presented via plots and a table. The exact solution shows that the modified Hartmann number, nanofluid volume fraction and heat sink tend to improve as the values of Shear stress (skin friction) for Cu – water nanofluid shows a comparative increase over Al2O3 and TiO2 nanofluids. Whereas the Radiation effect tends to decrease as the shear stress values for Cu–water nanofluids show a higher decline over Al2O3 and TiO2 nanofluids.
