In this work, the effects of temperature-dependent viscosity and thermal conductivity on the heat and mass transfer
behaviour of thermally radiated and chemically reacting MHD Micropolar fluid across a permeable stretched sheet in a
Darcy-Forchheimer porous medium were examined. Additionally, the impacts of Soret and Dufour in the presence of a
non-uniform heat source or sink are investigated. The coupled nonlinear partial differential equations regulating the fluid
flow are turned into coupled nonlinear ordinary differential equations by using Lie -group scaling transformations. The
Weighted Residuals Method (WRM) is used to solve the resulting coupled nonlinear ODEs, and the resultant solution is
compared with the fourth order Runge-Kutta method and shot approach. The influences of the emerging flow parameters
on the dimensionless velocity, microrotation, temperature and species concentration profiles are graphically presented
while the effects of some selected flow parameters on the skin friction coefficient, wall couple stress, heat and mass
transfer rates are tabulated.
