Abstract:
We numerically investigate a mixed convection
model for a magnetohydrodynamic (MHD) Jeffery fluid
flowing over an exponentially stretching sheet. The influence
of thermal radiation and chemical reaction is also
considered in this study. The governing non-linear coupled
partial differential equations are reduced to a set of
coupled non-linear ordinary differential equations by using
similarity functions. This new set of ordinary differential
equations are solved numerically using the Spectral
Quasi-Linearization Method. A parametric study of physical
parameters involved in this study is carried out and
displayed in tabular and graphical forms. It is observed
that the velocity is enhanced with increasing values of the
Deborah number, buoyancy and thermal radiation parameters.
Furthermore, the temperature and species concentration
are decreasing functions of the Deborah number.
The skin friction coefficient increases with increasing values
of the magnetic parameter and relaxation time. Heat
and mass transfer rates increase with increasing values of
the Deborah number and buoyancy parameters.
