Hybrid Nanofluid Flow And Heat Transfer Over A Nonlinear Permeable Stretching/Shrinking Surface

Purpose: This paper aims to investigate the steady flow and heat transfer of a Cu-Al2O3/water hybrid nanofluid over a nonlinear permeable stretching/shrinking surface with radiation effects. The surface velocity condition is assumed to be of the power-law form with an exponent of 1/3. The governing...
