Abstract |
|
|
| In this paper, we have considered the nonlinear coupled boundary-layer equations that describe the problem of injection or
extraction of fluid along the surface of an inclined wall embedded in a saturated porous medium. We obtain very accurate approximate
analytic solutions in closed-form by a direct method for the special cases l = 0 and l = 1. Furthermore, an accurate analytic series
solution is obtained by the modified Adomian decomposition method for the two limiting cases of free and forced convection by setting
Rak
Pex
= 0 and Rak
Pex 6= 0, respectively. |
