Abstract

The present article deals with magnetohydrodynamic boundary layer flow of an incompressible viscous fluid due to unsteady shrinking surface. Mathematical model of this mechanism has been constructed in the form of partial differential equations and then rehabilitated for coupled non-linear ordinary differential equations using similarity transformations. Though various conjectures have been proposed to explain the concept of boundary layer flow, we are presenting Adomian decomposition method (ADM) to simulate the solution of the present model. We used the diagonal padé approximant to achieve the better convergence in the solution of ADM. For the sake of validation, Adomian’s solution is compared with the two different techniques (Optimal HAM and Runge–KuttaFelburge method). The velocity profiles for various embedded parameters have been plotted and examined. Numerical values of skin-friction coefficient are calculated against various values of emerging parameters.
