Significance of activation energy in stratified flow of tangent hyperbolic fluid

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.
