Abstract
This article examines entropy generation in the peristaltic transport of nanofluid in a channel with flexible walls. Single walled carbon nanotubes (SWCNT) and multiple walled carbon nanotubes (MWCNT) with water as base fluid are utilized in this study. Mixed convection is also considered in the present analysis. Viscous dissipation effect is present. Moreover, slip conditions are encountered for both velocity and temperature at the boundaries. Analysis is prepared in the presence of long wavelength and small Reynolds number assumptions. Two phase model for nanofluids are employed. Nonlinear system of equations for small Grashof number is solved. Velocity and temperature are examined for different parameters via graphs. Streamlines are also constructed to analyze the trapping. Results show that axial velocity and temperature of the nanofluid decrease when we enhance the nanoparticle volume fraction. Moreover, the wall elastance parameter shows increase in axial velocity and temperature, whereas decrease in both quantities is noticed for damping coefficient. Decrease is notified in Entropy generation and Bejan number for increasing values of nanoparticle volume fraction.

Summary
Due to ample applications the nanofluids have gained a lot of interest among researchers. The nanofluids consist of particles of nanosize in the base fluid. Base fluids usually utilized for this purpose are kerosene oil, water, ethylene-glycol, etc. The nanoparticles used in the nanofluids are of different types including the metals, metallic oxides, oxides, carbides, carbon nanotubes, etc. The characteristics of the nanofluids highly depend upon the shape, size and material of the nanoparticles. The nanoparticles are efficient for the enhancement of thermal conductivity
