Abstract In present article a peristaltic analysis has been carried out to examine the nanofluid flow through the symmetric vertical channel. Three types of nanoparticles, copper oxide ( C u O ), silver (Ag) and silicon dioxide (SiO 2 ), are incorporated with base fluid as pure water. For this persistence the aspects of mixed convection and heat generation/absorption are accounted to observe the modifications in flow field as well as in fluid temperature. Viscosity is also considered which is determined by temperature. The large wavelength approximation with small Reynolds number is used to simplify the involved nonlinear terms in constitutive equations. The arising expressions for axial velocity, temperature profile, pumping characteristics and phenomenon of trapping are evaluated analytically under established physical conditions at boundaries. The solutions thus acquire is utilized to describe the impacts of various emerging parameters on important phenomena related to peristaltic motion. Results found that axial velocity depicts opposite variations in central and around the walls. Moreover, impact of heat generation parameter has shown increasing trend. It is also noticed that in pumping region, the pressure rise per wavelength increases (decreases) by increasing Grashof number, viscosity parameter and nanoparticles volume fraction. A comparative study is also explored for CuO, SiO 2 and Ag nanofluids and pure water.
