Effect of buoyancy force on an unsteady thin film flow of Al2O3/water nanofluid over an inclined stretching sheet

The present study looks at the heat transfer and the unsteady thin film flow of Al2O3 water nanofluid past an inclined stretching sheet having a buoyancy force effect. The boundary value problem solver (bvp4c) package in Matlab is utilized in solving the converted set of ordinary differential equati...
