MHD free convection Maxwell nanofluid flow through an exponentially accelerated vertical surface in the presence of radiation

Abstract

The unsteady MHD free convection Maxwell nanofluid flow through an exponentially accelerated vertical surface with the presence of radiation and chemical reaction is investigated in this present study. For obtaining numerical solutions, the governing partial differential equations (PDEs) are transformed into dimensionless partial differential equations (PDEs) with the as usual mathematical transformation. Explicit finite difference method (EFDM) is used for numerical solutions where ForTran programing language have been used as the main tool of investigations. The stability analysis technique (SAT) is used for choosing the appropriate values of parameters. Then, the obtained numerical results are affected by this various dimensionless parameters such as magnetic parameter (M), Maxwell parameter (Mx), Schmidt number (Sc), Grashof number (Gr), Lewis number (Le) and so on. The velocity, temperature and concentration profiles along with the skin friction coefficient (Cf), Nusselt number (Nu) and Sherwood number (Sh) are analysed for different perspective. Furthermore, the streamlines and isotherms are discussed for different interesting parameters in this work. Finally, the results are discussed after stability convergence test (SCT) by using graphics software tecplot-9 and comparison of our results with the previous results have been presented in a tabular form.
