Entropy Formation Analysis for the Peristaltic Motion of Ferrofluids in the Presence of Joule Heating and Fluid Friction Phenomena in a Plumb Duct

This study has been managed to evaluate the entropy growth during peristaltic transport of ferrofluids in a plumb duct. The selected ferrofluids are made of magnetite (Fe3O4) nanoparticles and engine oil. Moreover, heat transfer analysis is performed with Joule heating, viscous dissipation and thermal radiation effects. Mathematical formulation has been completed, which results into a set of ordinary differential equations. Exact solutions in the closed form have been computed for the momentum, energy and pressure gradient. Moreover, entropy generation due to heat transfer, thermal radiation, viscous dissipation and magnetic effects has been encountered. Graphical illustrations for emerging flow parameters like Hartmann number, Brinkman number, radiation parameter and dimensionless temperature difference have been prepared in order to study the physical sense of these particulars. The central point of the second law of thermodynamics is achieved by increasing the magnitude of the thermal radiation parameter. Streamlines are also graphed for different values of the amplitude ratio and the flow rate.
