Unsteady transport phenomena of hybrid Al2O3-Cu/H2O nanofluid past a shrinking slender cylinder

Theoretical investigations of unsteady boundary layer flow gain interest due to its relatability to practical settings. Thus, this study proposes a unique mathematical model of the unsteady flow and heat transfer in hybrid nanofluid past a permeable shrinking slender cylinder. The suitable form of s...
