Mathematical analysis of stagnation point flow in a micro polar fluid within a magnetic field environment

Abstract

The study explores how thermal radiation and chemical reactions influence the magneto hydrodynamic stagnation-point flow of a micropolar fluid over a stretching surface, along with heat and mass transfer effects, by formulating a mathematical model. It is presumed that the sheet's surface stretches in its own plane at a velocity that is proportional to the distance from the stagnation point The non-linear partial defferential equations that govern the motion have been reduced to the coupled non-linear ordinary defferential equations by using boundary layer approximation. The resulting system of equations is solved numerically using an implicit finite difference scheme combined with Newton's linearization method. The effects of various intriguing parameters on the flow and heat transfer are examined, and the obtained results are presented graphically for discussion.
