Abstract
The aim of this paper is to study the thermal radiation effects on the flow
and heat transfer of an unsteady magnetohydrodynamic (MHD) micropolar fluid over a
vertical heated nonisothermal stretching surface in the presence of a strong nonuniform
magnetic field. The symmetries of the governing partial differential equations are de-
termined by the two-parameter group method. One of the resulting systems of reduced
nonlinear ordinary differential equations are solved numerically by the Chebyshev spec-
tral method. The effects of various parameters on the velocity, the angular velocity, and
the temperature profiles as well as the skin-friction coefficient, the wall couple stress coefficient, and the Nusselt number are studied.
