Abstract
Purpose
The purpose of this paper is to introduce the Cattaneo-Christov heat flux model for an Oldroyd-B fluid.
Design/methodology/approach
Cattaneo-Christov heat flux model is utilized for the heat transfer analysis instead of Fourier’s law of heat conduction. Analytical solutions of nonlinear problems are computed.
Findings
The authors found that the temperature is decreased with an increase in relaxation time of heat flux but temperature gradient is enhanced.
Originality/value
No such analysis exists in the literature yet.
