Abstract
This investigation addresses the chemical reaction and double stratification effects in the flow induced by a nonlinear stretching surface with variable thickness. Flow formulation is developed using rheological expressions of Eyring–Powell liquid. Salient features of heat transfer are examined by considering non-Fourier heat flux model. Formulation is arranged for variable thermal conductivity. Flux model under consideration is the generalized form of Fourier’s classical expression with thermal relaxation time. Ordinary differential systems are obtained through implementation of appropriate transformations. Convergent series solutions are constructed. Non-dimensional velocity, temperature, concentration, skin friction and Sherwood number are displayed and discussed. It is anticipated that thermal and concentration stratified parameters decay the temperature and concentration respectively.
