Mixed convection peristalsis of carbon nanotubes with thermal radiation and entropy generation

Present study is prepared to explore the advantages of entropy generation in peristalsis of Single wall carbon nanotubes (SWCNTs) and Multiple wall carbon nanotubes (MWCNTs). Fluid is considered in a curved channel with radiative feature. Channel boundaries satisfy velocity slip condition. Flow equations subject to long wavelength are solved for pressure gradient, pressure rise per wavelength, stream function velocity and temperature. Brinkman number is employed as the perturbation quantity. Physical impact of pertinent parameters on considered flow quantities are described through graphs. Graphical results indicate that velocity and temperature are decreasing functions of CNTs volume fraction. It is seen that temperature difference parameter has opposite impact on entropy and Bejan number. Moreover heat transfer rate for SWCNTs is more than MWCNTs.
