A theoretical analysis is performed to study the flow and heat transfer characteristics of
magnetohydrodynamic mixed convection flow of a micropolar fluid past a stretching surface
with slip velocity at the surface and heat generation absorption. The transformed equations
solved numerically using the Chebyshev spectral method. Numerical results for the velocity, the
angular velocity, and the temperature for various values of different parameters are illustrated
graphically. Also, the effects of various parameters on the local skin-friction coefficient and the
local Nusselt number are given in tabular form and discussed. The results show that the mixed
convection parameter has the effect of enhancing both the velocity and the local Nusselt number
and suppressing both the local skin-friction coefficient and the temperature. It is found that
local skin-friction coefficient increases while the local Nusselt number decreases as the magnetic
parameter increases. The results show also that increasing the heat generation parameter leads to
a rise in both the velocity and the temperature and a fall in the local skin-friction coefficient and
the local Nusselt number. Furthermore, it is shown that the local skin-friction coefficient and the
local Nusselt number decrease when the slip parameter increases.
