Entropy generation analysis of peristaltic flow of magneto-nanoparticles suspended in water under second-order slip conditions

Peristalsis of magneto-nanoparticles suspended in water was investigated in this study. Fe3O4-water nanofluid was utilized for two-dimensional flow in channel, which was considered symmetric with compliant walls. Uniform magnetic field was applied and temperature equation was arranged for viscous dissipation. Also, second-order velocity and thermal slip conditions were utilized. Small Grashof number led to the perturbation solution. Examination of entropy generation was also carried out. Maxwell and Hamilton-Crosser models was used. The analysis was based on the comparative study of these two models representing the cylindrically and spherically shaped particles. Graphs for velocity, temperature, entropy generation, and Bejan numbers were plotted under the influence of sundry variables. Trapping was observed via plotting streamlines.
