Abstract
Purpose
The purpose of this paper is to introduce the concept of improved Fourier–Fick laws subjected to variable fluid characteristics. Flow analysis in the stagnation region of Oldroyd-B fluid is elaborated. Heat generation is present.
Design/methodology/approach
Optimal homotopy analysis method is used to obtain convergent solutions.
Findings
The outcomes reveal reduction in penetration depths of temperature and concentration due to involvement of thermal and solutal relaxation times of fluxes.
Originality/value
As per the authors’ knowledge, such analysis has not yet been reported.
