Abstract : The effects of steady electro-osmotic flow (EOF) and magnetohydrodynamics (MHD) with variable viscosity and the reactive fluid flow thermal conductivity are investigated with varying exponential temperature-dependent properties. The dimensionless variables are used to transform the governing equations of the flow to an invariant model. Thus, steady variable viscosity, thermal conductivity momentum and energy-coupled nonlinear equations are solved using the Weighted Residual method and a collocation integrating scheme. The graphical representation of results is done to effectively study the effects of the thermophysical behaviour of the model. The influence of electro-osmotic and magnetic fields on the fluid flow was significant, as Lorentz force retarded the flow while thermal conductivity dampened the fluid flow. Viscosity enhanced the temperature field due to the thickness of the thermal boundary layer as the parameter increased. Also, in conclusion, variable viscosity and thermal conductivity increased the velocity and temperature profiles for steady EOF-MHD flow. This information will be helpful in the chemical processing industry, combustion industry and allied engineering.
