Electro-kinetic and viscous dissipation has extensive applications in various fields such as electronic packaging, mechanical and thermal engineering, aerospace, and biotechnology. The present work aims to investigate numerical heat and mass transfer by Maxwell Nano-fluid flow over a stretchable surface in the presence of viscous dissipation and electro-osmosis effects. One of the features of this work is the relaxation time provided to the momentum boundary layer arising from considering the Maxwell model. Another important feature is the thermophoresis and Brownian diffusion due to the inclusion of Buongiorno's model. The objective of this paper is to study the effects of viscous dissipation and electroosmosis forces on heat transfer using Maxwell nanofluid. The governing equations, which were two-dimensional partial differential equations, were transformed into ordinary differential equations through appropriate similarity transformations. Then the system of coupled ordinary differential equations is solved numerically using the bvp4c solver in Matlab software for given values of the physical parameters. The outcomes are presented graphically as velocity, temperature, and concentration profiles. Physical quantities of interest, such as the local Nusselt number, skin friction coefficient, and Sherwood number, are tabulated.
