Analysis of activation energy on the Johnson–Segalman nanofluid through an asymmetric microchannel: Numerical study

Abstract

Activation energy and thermal radiation as a means of heat transfer are significant and fascinating phenomena for scientists and researchers because of their significance in cancer treatment. As a result, heat kills cancer cells and shrinks tumors, making hyperthermia therapy a cutting-edge cancer treatment. This paper examines the peristaltic motion of a Johnson–Segalman nanofluid across an asymmetric pliable microchannel under the impact of activation energy. We obtained the governing equations for the non-Newtonian nanofluid. Partial differential equations (PDEs) are reduced to ordinary differential equations (ODEs) under the assumption of large wavelengths and tiny Reynolds number assumptions. The flow patterns and trapping phenomena were numerically generated using the NDSolve command of the computational mathematical software Mathematica. The influence of important liquid parameters was examined with graphical representations of the results. The current study reveals an enhancement in the heat generation parameter, an enhancement in the temperature and a reduction in the concentration.
