文摘

Global entropy in water–Al2O3 nanofluid flow in a vertical microchannel was investigated. Effects of nonlinear thermal radiation, slip and magnetic parameters were examined. Optimum values of slip flow with minimum entropy were found. Optimum values of Grashof number with maximum heat transfer were derived. Effects of convective-radiative heat transfer on boundary surfaces were examined.
