Abstract
Double diffusion models with Carreau rheology strain-relations and correlations for thermal physical properties are used to model double diffusion phenomenon in Carreau liquid passing a wedge-shaped body. Normalized conservation equations are solved numerically using finite element method (FEM). Linear shaped functions are used in weak forms of models under Galerikin approximations. Convergence and mesh free analysis are performed and results are validated. The numerical simulations against parametric analysis are also observed. Suspension of hybrid nano-structures has significantly increased the effectiveness of thermal conductivity and an enhance in thermal and mass transport is observed. An increase in thermal radiations causes a remarkable decrease in temperature. Weissenberg parameter decreases velocity of Carreau liquid in the presence of magnetic field and hybrid nano-structures. The chemical reaction has an impact on the diffusion of specie from wedge into fluid increases for the case of generative chemical reaction whereas opposite trend is noted in case of destructive chemical reaction.
