Abstract: This research looks at the influence of absorbing radiation and a heat source on unsteady magnetohydrodynamic (MHD) fluid flow across a flat, permeable, moving plate holding hyperbolic tangent fluid. Under a longitudinal magnetic field, the plate travels at a constant velocity while submerged in a homogenous porous media. Hyperbolic tangent nanofluids are critical for cooling devices that create a lot heat. The issue is represented using mass, momentum and energy conservation principles and the governing equations of nonlinear partial differential equations (NPDEs) are translated into dimensionless form using similarity transformation. The resultant equations are solved with the finite element technique. The finite element approach (FEM) is a numerical approach for solving complicated differential equations that divides the problem area into smaller, simpler components known as finite elements. It offers an effective and adaptable technique to understanding physical phenomena including fluid flow, heat transport and structural mechanics. Furthermore, the impacts of various factors on the skin friction coefficient Nusselt number and the transfer rate of mass (portrayed by the Sherwood number) at the outer layer are extensively examined, including “the thermal and solvent Grashof number (Gr and Gc), Eckert number (Ec), Lewis number (Le), buoyancy ratio parameter (Nc), thermophoretic parameter (Nbt), heat source or sink (Q), radiation parameter (R), Prandtl number (Pr), magnetic field (M) and Darcy number (Da).” Both qualitative and quantitative analysis depicts the results for the drag coefficient, heat transfer and mass transfer rates. It is worth noting that both Gr and Gc faster to enhance in the velocity boundary layer, previously studied literatures are not examined all these parameters all at once.
