Further Results on Nonlinearly Stretching Permeable Sheets: Analytic Solution for MHD Flow and Mass Transfer

Abstract EN

The steady magnetohydrodynamic (MHD) flow and mass transfer of an incompressible, viscous, and electrically conducting fluid over a permeable flat surface stretched with nonlinear (quadratic) velocity uw(x)=ax+c0x2 and appropriate wall transpiration is investigated.

It is shown that the problem permits an analytical solution for the complete set of equations with magnetic field influences when a fictitious presence of a chemical reaction is considered.

Velocity and concentration fields are presented through graphs and discussed.

The results for both skin friction coefficient f′′(0) and mass transfer gradient c′(0) agree well with numerical results published in the literature.
