Abstract
Present work is made to study the effects of double stratified medium on the mixed convection boundary layer flow of Eyring-Powell fluid induced by an inclined stretching cylinder. Flow analysis is conceded in the presence of heat generation/absorption. Temperature and concentration are supposed to be higher than ambient fluid across the surface of cylinder. The arising flow conducting system of partial differential equations is primarily transformed into coupled non-linear ordinary differential equations with the aid of suitable transformations. Numerical solutions of resulting intricate non-linear boundary value problem are computed successfully by utilizing fifth order Runge-Kutta algorithm with shooting technique. The effect logs of physical flow controlling parameters on velocity, temperature and concentration profiles are examined graphically. Further, numerical findings are obtained for two distinct cases namely, zero (plate) and non-zero (cylinder) values of curvature parameter and the behaviour are presented through graphs for skin-friction coefficient, Nusselt number and Sherwood number. The current analysis is validated by developing comparison with previously published work, which sets a benchmark of quality of numerical approach.

Summary
An analysis of stratification phenomena in non-Newtonian fluids received substantial attention due to its practical applications in engineering and industrial areas. Khader and Megahed[22] presented numerical findings (utilizing Chebyshev finite difference method) of Eyring-Powell fluid flow induced by time dependent stretching sheet with internal heat generation effect. Convection and thermal diffusion effects on Eyring-Powell fluid flow induced by non-linear stretching surface. The above-mentioned literature survey reflects that the investigators restricted their study to horizontal geometry, so the double stratification effects with mixed convection on Eyring-Powell fluid flow carried by an inclined stretching cylinder is not investigated so far. Current study aims to fill the gap and seems to be a first attempt in this direction to identify the dual stratification effects on Eyring-Powell fluid flow along an inclined stretching cylinder in the presence of mixed convection phenomena and heat generation process. Skin friction-coefficient, local Nusselt and Sherwood numbers are numerically computed against several involved parameters
