Tribological perceptions into shear thinning fluid flow: A quantitative analysis using rotating disk phenomenon

In the realm of tribology, the growing landscape of engineering applications has brought about significant developments but, despite such advancements in industrial applications, there remains a gap in understanding the numerical investigation of the flow, surface frictional forces as well as thermal characteristics in a rotating disk with nanoparticles, incorporating chemical reactions and velocity slip conditions. So, in the context of rising concerns, this article is of paramount importance for the rheology and friction caused by a rotating disk with the above physical phenomena. Numerical solutions are presented with the help of standard shooting scheme in conjunction with the 5th order Runge-Kutta method. The governing partial differential equations (PDEs) for the fluid flow are transformed into ordinary differential equations (ODEs) using new variables to facilitate the utilization of the Runge-Kutta 5th order method. The primary focus is to obtain the significance of fluid parameters, partial slip, chemical reactions, Brownian motion, and thermophoresis parameters. The implications of physical parameters are elucidated through graphical representation and discussed in detail.
