Shape factor effect of radiative Cu-Al2O3/H2O hybrid nanofluid flow towards an EMHD plate

This paper aims to analyze the effects of different nanoparticles shape factor, EMHD and radiation parameters for the Cu–Al2O3/H2O nanofluid flow towards a stretching/shrinking Riga plate. The model is simplified into a set of ordinary (similarity) differential equations using the similarity transfo...
