Abstract
Purpose The purpose of this paper is to address double stratification and activation energy in flow of tangent hyperbolic fluid. Flow is induced by non-linear stretching sheet of variable thickness. Heat flux by Cattaneo-Christov theory is implemented. Design/methodology/approach Non-linear system is computed for the convergent solutions. Attention is particularly focused to the velocity, temperature and concentration. Findings It is found that temperature and thermal layer thickness are decreased for larger stratification. Originality/value In view of aforementioned communication, the aim of the present study is fourfold: First, to inspect stagnation point flow of tangent hyperbolic liquid by a stretched sheet; second, to discuss effect of non-Fourier heat flux and double stratification; third, to investigate activation energy; and fourth, to examine variable thickness effect.
