Laminar boundary layers in MHD three dimensional flow past a semi‐infinite uniformly moving vertical plate with variable sinusoidal suction

The ongoing problem deals with the investigation of a naturally convective 3D hydromagnetic flow of a fluid that is incompressible, electrically conducting, having viscous properties and passes through a uniformly moving porous plate placed vertically. A magnetized field pointed toward the fluid area having uniform strength is placed mutually perpendicular to the plate. The effects of diffusion‐thermo, thermal radiation, and thermal diffusion are also checked. The heat and mass transfer are constant, while the sinusoidal suction velocity varies at the plate. The equations determining the flow model are solved and analytical solutions are obtained, using the asymptotic series expansion approach. So, the main goal and novelty of the work is that here the simultaneous effects of Dufour and Soret are taken into account in addition to radiation. This type of scenario is rare in existing literature. One of the notable findings of this study is that when the Dufour and the sinusoidal suction velocity parameter are amplified, the shear stress increases.
