Abstract

The present study analyses the unsteady electro magnetohydrodynamic (EMHD) stagnation point flow in a hybrid nanofluid concerning a stretching/shrinking sheet to which boundary-layer theory is applied. By simplifying the governing differential equations, the ordinary differential equations system is accomplished utilising the appropriate similarity conversions. The bvp4c method in the MATLAB systems software is implemented since this approach is competent in initiating non-uniqueness solutions once sufficient initial assumptions are made available. The results reveal that the skin friction coefficient and the local Nusselt number rise by the inclusion of nanoparticles. The electrical and magnetic field coordination result from the Lorentz force emerges to postpone the progression of the fluid. Moreover, the heat transfer characteristic is exaggerated when the electric and magnetic parameters are involved in the hybrid nanofluid stagnation point flow. The unsteadiness parameter, however, has a decreasing impact on the heat transfer performance.
