Effect of Stefan blowing and magnetic dipole on chemically reactive second-grade nanomaterial flow over stretching sheet

Abstract

A numerical examination is executed to scrutinise the heat and mass transfer characteristics in a stagnation point flow of viscous ferromagnetic second-grade liquid over a stretching sheet. Moreover, features of chemical reaction, magnetic dipole and Stefan blowing aspects are presented in this novel attempt by employing Buongiorno model in the flow problem. Similarity transformations are used to convert the governing partial differential equations into ordinary differential form, which are then solved using classical Runge–Kutta (RK) process with shooting technique. The solutions for the flow, thermal, concentration, skin friction, rate of heat and mass transfer characteristics are attained numerically and presented graphically. The significant results of the current study are that the rising values of ferromagnetic interaction parameter declines the velocity. The improvement in values of Brownian motion and thermophoresis parameter augments the heat transfer. Furthermore, the rising values of thermophoresis parameters decline the heat and mass transfer rate.
