Abstract
In this article, research has focused on the effects of Joule heating, thermal radiation, and viscous dissipation on the flow of unsteady MHD nanofluids over a porous stretched sheet. The model composed of equations is modified to propose an acceptable dimensionless character. With the aid of similarity transformations, the non-linear PDEs transform into the non-linear ODES. The Kellerbox is a method used in MATLAB software to solve a few pairs of transformed equations and subsequently describe altered boundary conditions. In addition to the outcomes for the distinct nanofluid types, there is a table and graphical representation of the properties of Al 2 O 3 and Cu nanofluids. The tabular and graphical findings show the physical relevance of the effort level. The findings are shown to be quite satisfactory in agreement with the work which was already outlined in the scientific literature. Displayed graphically and in tabular form are the results that quantify the physical significance of the effort. The Cu nanofluid exhibited much greater thermal gradients compared to the Al 2 O 3 nanofluid for all parameters S θ , A , B , R , Du , and Ec. When contrasting the two nanofluids, this came out as the result. The velocity patterns of Al 2 O 3 nanofluid were much greater than those of Cu nanofluid when comparing the two materials concerning the variables M , K p , S , and f w .
