Abstract

In this paper, we attempt to analyze the effects of radiation and chemical reactions on laminar boundary layer flow of an electrically conducting unsteady viscoelastic incompressible fluid flow along a vertical semi-infinite plate passing through porous channel. The coupled nonlinear partial differential equations for energy, momentum, and mass diffusions are solved analytically with the use of perturbation technique. Moreover, the analytical expressions for fluid velocity, temperature, and concentration distributions are obtained and interpreted using the software MATLAB. The enhancement of velocity is prominent with the growth of Gr, Gm, Nr and Kr but a reverse pattern is observed with the rise of Pr. The physical values of skin friction coefficient, Nusselt number and Sherwood number are estimated remembering their importance in engineering and technology fields. The graphical augmentation are instituted in possible cases for various viscoelastic parameters in combination of other dimensionless flow parameters. The simulations presented here relate to metal extraction in chemical and polymer processes.
