The Marangoni stream generated due to the gradient of surface temperature and plays an important role in silicon melt, spray, atomic reactors and the thin fluid film. The Marangoni convection liquid film graphene oxide water (GO-W) and ethylene glycol (GO-EG) nanofluid over an unsteady extending sheet are addressed in this work. The two sorts of (GO-W) and (GO-EG) water-based nanofluids have been utilized for the thermal spray analysis. The thickness of the nanoliquid film kept variable for the stable spray rate. The transformed equations of the flow problem have been solved using the optimal homotopy analysis method (OHAM). The impact of the physical parameters versus velocity, and temperature pitches under the influence of the Marangoni convection has been obtained and discussed.
