Thisresearch investigated the flow and heat mass transmission of a thermal Buongiornonanofluid film caused by an unsteady stretched sheet. The movement of the nanoparticles throughthe thin film layer is caused by the strength of the heat flow and the stretching force of the sheetworking together. The thermal thin-film flow and heat mechanism, and the properties of mass transferalong the film layer, were comprehensively investigated. The consequences of the heat generation,magnetic field, and dissipation phenomenon were also thoroughly examined. Using appropriatedimensionless variables, the fundamental time-dependent equations of thin film nanofluid flowand heat mass transfer were modeled and converted to the ordinary differential equations system.Mathematica version 12 is the software that was used to build the numerical code here. Next, theshooting technique was applied to numerically solve the transformed equations. The elegance ofthe shooting technique and evidence of the consistency, dependability, and precision of our acquiredresults is that the results are more effective than those for the thin film nanofluid equations that arenow available. There is a significant degree of consistency between the recently calculated resultsand the results that have been published for a limiting condition. Investigations were conducted intothe effects of a variety of parameters on the flow of nanoliquid films, including the Nusselt number,skin friction, and Sherwood number. In addition, a detailed overview of the physical embeddedparameters is provided through graphs and tables. However, the important features of the mostrelevant outcomes are the effects of higher porous and unsteadiness parameters on minimizing thethickness of the thin film; and the viscoelastic parameter has the reverse effect. Additionally, it is seenthat the temperature profile improves as a result of higher thermophoresis and Brownian motionparameter values.
