This article aims to investigate the mixed convective peristaltic transport of water-/kerosene-oil-based nanofluids composed of carbon nanotubes (SWCNT and MWCNT) as nanoparticles. An asymmetric inclined channel is considered. An incompressible liquid saturates the porous space. Energy equation involves the viscous dissipation and heat source/sink effects.Mathematical formulation is presented using second-order velocity and thermal slip conditions. The problems have been simplified using lubrication approach. The resulting nonlinear system is solved numerically employing NDSolve of MATHEMATICA. A detailed analysis of the results is given through graphs and bar charts. Results show that the axial velocity and temperature are decreasing function of nanoparticle volume fraction. Second-order slip and thermal slip parameters on velocity and temperature have reverse effect. Moreover enhancement is seen in the heat transfer rate at thewall for larger nanoparticle volume fraction. However ,such enhancement is larger for theSWCNT case thanMWCNT. Heat transfer rate decreases for porosity, second-order slip and thermal slip parameters.
