Abstract: | An analytical study is made for wall effects in non-Darcy mixed convection from vertical impermeable surfaces embedded in
a saturated porous medium. The governing equations are transformed into a dimensionless form by non-similar transformation
to cover both forced and natural convection dominated regimes. Two different dimensionless parameters that measure the strength
of mixed convection were found in both regimes. The parameters of forced convection dominated regime can be related to those
of natural convection dominated regime. An approximate analytical solution for the governing equations was obtained. Temperature
and velocity profiles for both regimes are presented.
