Abstract

The present work deals with the periodic Magnetohydrodynamics (MHD) effect on a transient boundary layer flow of naturally convective non-Newtonian (viscoelastic) fluid and nanofluids along a semi-infinite vertical porous plate with thermal radiation effect. The aim is to mathematically determine the heat and mass transfer flow fields and their area of existence. Explicit solutions are then derived for the momentum, temperature and concentration flow fields. The nonlinear partial differential equations (PDEs) are transformed into a system of coupled nonlinear ordinary equations (ODEs) by different similarity transformations and then solved by explicit finite difference method (EFDM). For optimizing the system parameter and accuracy of the system, the stability and convergence (SCA) analysis have been carried out. To obtain the numerical results, the computer programming language FORTRAN 6.6a has been used. A numerical comparison with previously published results is shown in tabular form to validate the present numerical approach. The effects of flow parameters such as magnetic field parameter (M), Prandtl number (Pr), skin friction (Cf), Nusseltnumber (Nu), thermal radiation parameter (R), Lewis number (Le) involved in the solution on velocity, temperature, and concentration distribution have been shown graphically and discussed qualitatively. Furthermore, streamlines and Isotherms line presentation for momentum and thermal boundary layer thickness for periodic magnetic field parameter (M), have been shown.
