Abstract

In the present study, an analytical investigation on the entropy generation examination for viscoelastic fluid flow involving inclined magnetic field and non-linear thermal radiation aspects with the heat source and sink over a stretching sheet has been done. The boundary layer governing partial differential equations were converted in terms of appropriate similarity transformations to non-linear coupled ODEs. These equations were solved utilizing Kummer's function so as to figure the entropy generation. Impacts of different correlated parameters on the profiles velocity and temperature, also on entropy generation were graphically provided with more information. Based on the results, it was revealed that the existence of radiation and heat source parameters would reduce the entropy production and at the same time aligned magnetic field, Reynolds number, dimensionless group parameter, Hartmann number, Prandtl number, and viscoelastic parameters would produce more entropy. The wall temperature gradient was additionally computed and compared with existing results from the literature review, and demonstrates remarkable agreement.
