Hydromagnetic micropolar fluid flow over a stretching sheet under viscous dissipation, thermal radiation and Dufour–Soret effects

In the present investigation, we investigated the chemically reactive, laminar flow of a micropolar fluid over a stretching sheet in the presence of a transverse magnetic field, thermal radiation and the mutual effect of Soret–Dufour and viscous dissipation. The governing partial differential equations are converted into a system of nonlinear ordinary differential equations for finding the mathematical solutions and the transformed system is solved using the bvp4c algorithm in the MATLAB environment. Effects of different physical factors on dimensionless velocity, microrotation, temperature and concentration profiles are addressed and illustrated graphically. When the Schmidt number is low, it indicates that the momentum diffusivity dominates over the mass diffusivity.
