Peristaltic transport of copper–water nanofluid saturating porous medium

• Peristaltic transport of copper–water nanofluid through an asymmetric channel is analyzed in this study.
• The copper–water nanofluid saturates a uniform porous medium.
• Two phase flow model is used for the analysis.
• Viscous dissipation and heat generation/absorption are taken into account.
• Resulting system of equations is solved numerically and obtained numerical results are graphically analyzed.

Prime goal of present study is to model the problem for peristaltic transport of copper–water nanofluid in an asymmetric channel. The fluid fills porous space. Analysis is carried out in the presence of mixed conviction, viscous dissipation and heat generation/absorption. Long wavelength and low Reynolds number approximations are utilized in problem formulation. Numerical computations are presented for the axial velocity, pressure gradient, streamlines, temperature and heat transfer rate at the boundary. Graphical analysis is carried out to examine the effects of sundry parameters on flow quantities of interest. Results revealed that the axial velocity of copper–water nanofluid decreases with an increase in the nanoparticle volume fraction. Copper nanoparticles prove effective coolant since they sufficiently reduce the fluid temperature and show increase in the heat transfer between the fluid and solid boundary. Moreover temperature of the fluid decreases by increasing the permeability of porous medium.
