A scientific report on heat transfer analysis due to generated and absorbed heat over an oscillatory stretching sheet: A finite difference-based study

Abstract

A non-Newtonian liquid flow across a stretching sheet is relevant to various industrial applications, including extruding plastic sheets and stretching plastic films. In connection with this, the effect of endothermic and exothermic chemical reactions on the flow of rate-type liquid via an oscillatory stretching sheet in the presence of permeable media with the Maxwell liquid model is examined in the current study. Scientists and engineers may improve the effectiveness of chemical reactions or heat transfer by designing systems with optimal flow and researching how reactions affect flow. The present study's governing partial differential equations (PDEs) are transformed into their non-dimensional form using similarity variables. The finite difference method (FDM) is used to solve the resultant equation numerically. Outcomes disclose that the temperature profile declines as the activation energy and unsteady parameters increase. The influence of the Maxwell and unsteady parameters on the velocity profile with respect to time is represented. The increase in the values of chemical reaction upsurges the thermal profile. As the activation energy parameter and unsteady parameter upsurge, the thermal profile declines. The concentration profile declines as the chemical reaction parameter and the ratio of oscillating frequency to stretching rate values increases.
