Abstract EN
The MHD flow due to the nonlinear stretching of a porous sheet is investigated.
A closed form solution is obtained when the stretching rate is inversely proportional to the distance from the origin.
Otherwise a uniformly valid asymptotic expansion, for large magnetic interaction number β ~ ∞ , is developed.
It coincides with a homotopy perturbation expansion for the problem.
The asymptotic/homotopy perturbation expansion gives results in excellent agreement with accurate numerical results, for large as well as small values of β .
For large β , the expansion, being asymptotic, needs a small number of terms, regardless of the mass transfer rate or the degree of nonlinearity.
For small β , the expansion is a homotopy perturbation one.
It needs considerably increasing number of terms with higher injection rates and/or with stretching rates approaching the inverse proportionality.
It may even fail.
