Abstract:

This research purposes to analysis the impact of porous media and nonlinear thermal radiation on the magnetohydrodynamic (MHD) boundary layer flow of Williamson nanofluid across an exponentially stretched sheet using Darcy Forecheimer Model. The conservative equations for mass, momentum, and energy are transformed into ordinary differential equations using an appropriate similarity transformation. The bvp4c function then employed to solve the equations numerically. The major results show that the velocity distribution improves with uprising the buoyancy parameter. Increased buoyancy and thermal radiation are other factors contributing to elevated fluid temperature. Additionally, the fluid velocity decreases with increasing magnetic parameters.
