Thermodynamic analysis of an hydromagnetic internal heat generating variable-viscosity channel flow with non-uniform wall temperature

Abstract

This study examines the influence of magnetic intensity and internal heat generation on a flow system with variable-viscosity channel with varying wall temperatures. The fluid is assumed to be steady, incompressible with both the variable viscosity and internal heat generation to be a linear function of temperature. The approximate solutions are secured by using Adomian decomposition method (ADM) for the momentum and energy distributions as well as the rate of entropy generation and other thermophysical aspects of the flow regime under the impact of both the magnetic influence and internal heat generation are illustrated in tables and graphs.
