Modelling and analysis of heat transfer in MHD stagnation point flow of Maxwell nanofluid over a porous rotating disk

The study of fluid dynamics in the context of flow across a rotating disk is highly important since it has extensive applications in multiple industries, as well as in engineering and scientific fields. The objective of our current research is to investigate the heat transfer in the vicinity of a Stagnation Point of a Maxwell nanofluid flow passing over a porous rotating disk. A rotating disc is a phenomenon where a circular arc is formed at every point on the disc as it rotates uniformly around an axis. The shear stress at the interface between the disc and the spinning fluid provides information about the amount of power required to overcome friction and move the disc and the heat transfer is influenced by the alterations in the flow field inside the region. The heat and mass movement are studied in the context of a chemical process. Firstly, convert the PDEs into ODEs, suitable self-similarity transformation is used. After applying transformations, for graphical purpose we have used the Bvp4c technique. A variety of graphs (2D, Contour, vector plots, and Stream lines) and tables depict the impact of active parameters on the fluid's capacity to transfer significance. Velocity outline decreases for the greater values of the Deborah number values. The temperature profile improved with an improvement in the Nb parameter, while the opposite trend we noticed on ϕ(ζ). The findings of this study will have advantages in various fields, including transportation operations, architectural design systems, increased oil recovery systems, and medicinal applications that utilize nanofluids.
