Exact Analysis of Diffusion-Thermo Effect on MHD Natural Convective Flow Past an Oscillating Vertical Plate with Chemical Reaction and Thermal Radiation in Porous Medium

The primary goal of this investigation is to explore the impact of diffusion-thermo on the flow characteristics of MHD natural convection via a permeable medium past an infinitely oscillating upright plate, while accounting for chemical reaction and thermal radiation effects. The Laplace transformation approach is employed to solve the governing equations for species continuity equation, energy and momentum. The simulation findings show that thermal radiation increases the primary fluid velocity while decreasing the secondary fluid velocity. Furthermore, increasing the Dufour number (Du) results in higher temperature fields as well as an increase in both primary and secondary fluid velocities. Also, the diffusion-thermo effect contributes to improve the temperature field. The equation for skin friction is obtained and graphically shown. Three-dimensional surface plots are used to demonstrate the Nusselt and Sherwood numbers. In addition, graphical representations are used to portray the effect of non-dimensional factors on concentration, temperature, and velocity patterns.
