Abstract In this paper, we present a numerical method based on cubic B-spline function for studying the effects of thermal radiation and mass transfer on free convection flow over a moving vertical porous plate. Similarity transformations reduced the governing partial differential equations of the fluid flow to a system of nonlinear ordinary differential equations which are solved numerically using a cubic B-spline collocation method. The effects of various physical parameters on the velocity, temperature, and concentration distributions are shown graphically, and the numerical values of physical quantities like skin friction, Nusselt number, and Sherwood number for various parameters are presented in tabular form and discussed.

The aspiration of the mechanism is the impacts of radiation and mass transfer on the transient free convection flow of a dissipative fluid with the vertical Porous plate by taking into a consideration of the viscous dissipation. The governing equations for the one-dimensional model are solved with proper boundary conditions. The radiative heat transfer in the limit of the optically thick fluid is described. The momentum coupled equation with the energy and mass diffusion equations are solved by explicit finite difference method (EFDM). For Tran programming language is used as the main tool for calculating the simulating results. A parametric evaluation displaying the influence of distinct flow parameters on velocity profile, transient temperature and concentration are outlined graphically with the help of tecplot-9. Finally, a comparison of the present study with the previous study has been deliberated for different interesting parameters.
