Abstract
Peristalsis of carbon nanotubes (SWCNTs, MWCNTs) submerged in water through an inclined asymmetric channel is addressed in the current work. Such mechanism is disclosed in the presence of Hall effect, viscous dissipation, and Soret and Dufour effects. Convective heat transfer at the boundaries is incorporated by utilizing efficient thermal conductivity of nanoliquid. Low Reynolds number and long wavelength approximation are used for mathematical modeling. Resulting nonlinear set of equations is solved for pressure gradient, velocity, temperature and concentration. Impact of various variables on the axial velocity, pressure rise, pressure gradient, temperature, concentration, heat transport at boundaries and streamlines are discussed via their respective curves. Comparison between SWCNTs (single-wall carbon nanotubes) and MWCNTs (multiwall carbon nanotubes) is documented. Furthermore, submerging carbon nanotubes in water declines the velocity and temperature. In addition, heat transfer at the boundaries enhances by increasing volume fraction of carbon nanotubes. SWCNTs nanofluid shows higher velocity and concentration when compared with MWCNTs nanofluid. MWCNTs nanoliquid displays higher temperature than SWCNTs nanoliquid.
