Thermodynamic analysis of a variable viscosity reactive hydromagnetic couette flow within parallel plates

Abstract

This investigation is to consider the impact of a temperature-dependent variable viscosity of a reactive hydromagnetic Couette fluid flowing within parallel plates. The variable property of the fluid viscosity is thought to be an exponential relation of temperature under the impact of magnetic strength. The differential equations controlling the smooth movement of fluid and energy transfer are modeled and solved by using the series solution of modified Adomian decomposition technique (mADM). The outcomes are shown in tables and graphs for different estimations of thermophysical properties present in the flow regime together with the rate of entropy generation and irreversibility distribution outcome.
 Keywords: Reactive fluids, Couette Flow, variable viscosity, hydromagnetic and modified Adomian decomposition method (mADM).

The effects of variable viscosity on magnetic field intensity with heat, mass transfer over a vertical plate

“…It is a measure of internal resistance to the flow of a fluid when subjected to shear stress or tensile stress. Fluids that show stress resistance are termed viscous fluids while those that do not exhibit resistance to shear stress are referred to as ideal fluids or inviscid fluids (Hassan, Lawal, & Amurawaye, 2020) [1]. The viscosity of a fluid depends on various factors such as temperature, pressure, and shear rate.…”
