Abstract

Abstract: This paper addresses the effects of axisymmetric magnetohydrodynamic stagnation point flow of nanofluid through the lubrication of power‐law fluid by taking the general slip at the interfacial condition. The impacts of radiated chemical reaction, thermophoresis, and Brownian motions are further accounted. The fluid is impinging orthogonally on the surface via power‐law slim coating liquid lubrication. The partial differential system is governed for both the lubricant and the base fluid. Using dimensional analysis, the arisen partial differential system is modified to ordinary differential systems subject to nonlinear boundary conditions. An implicit numerical technique namely the Keller‐Box method is executed to formulate the solution of developed nonlinear expressions. The influence of different involved constraints on quantities of interest are sketched and discussed. The effects of the skin friction coefficient, heat transfer, and concentration rate at the surface are given and analyzed. The condition from full slip to the no‐slip can be achieved from the present solution. The obtained solutions are matched through the existing data and observed good agreement.
