Time-dependent flow of UCM fluid with chemical reaction, thermal-diffusion and diffusion-thermo effects

Abstract

Purpose

The authors presented the time-dependent flow of an upper-convected Maxwell (UCM) fluid in the presence of chemical reaction, thermal-diffusion and diffusion-thermo effects. The paper aims to discuss these issues.

Design/methodology/approach

Recent technique namely homotopy analysis method (HAM) is utilized to compute the solution of the problem.

Findings

Chemical reaction has opposite effects on the concentration field for the destructive and constructive cases. The Deborah number acts as a retarding agent.

Originality/value

Combined effects of thermal-diffusion, diffusion-thermo and chemical reaction are analyzed.
