Abstract: An analysis has been carried out for the radiative MHD flow of an aqueous ethylene glycol nanofluid past a two-way exponentially extending lamina. Appropriate transformation is used to reduce the nonlinear partial differential system to an ordinary differential system. The resulting nonlinear ordinary differential system is solved numerically using fourth order Runge Kutta shooting method for the satisfaction of asymptotic boundary condition. The velocity and temperature sketches of copper and alumina in aqueous ethylene glycol (a-EG) nanofluid for the present physical stratum are obtained and displayed graphically by fixing various values for pertinent factors of the problem namely, velocity ratio factor (λ), magnetic interaction factor (M), nanoparticle volume fraction (φ), exponential coefficient factor(A) and temperature-radiation factor (Rd) fixing the Prandtl number of the core fluid (a-EG) constant at 25.825 skin friction coefficient and rate of heat transfer for various factors of the problem are tabulated and compared with the existing results in the literature. Finally numerical simulation with comparisons is provided to demonstrate the effectiveness of the obtained result.
