### Numerical study for mixed convection flow of Oldroyd-B nanofluid subject to activation energy and binary chemical reaction

**ABSTRACT**

This attempt discusses mixed convection Oldroyd-B nanoliquid flow over a doubly stratified surface in existence of activation energy. Impacts of Brownian diffusion and thermophoretic are additionally accounted. The non-linear frameworks are simplified by suitable variables. Shooting method is utilized to develop numeric solution of resulting issue. Graphs have been composed just to explore that how concentration and the temperature are impacted by different developing flow factors. Mass and heat transport rates are additionally tabulated and dissected. Furthermore, the temperature and concentration distributions are enhanced for larger thermophoresis parameter.
