The present analysis discusses the peristaltic flow of a nanofluid in a diverging tube. This is the first article on the peristaltic flow in nanofluids. The governing equations for nanofluid are modelled in cylindrical coordinates system. The flow is investigated in a wave frame of reference moving with velocity of the wave c. Temperature and nanoparticle equations are coupled so Homotopy perturbation method is used to calculate the solutions of temperature and nanoparticle equations, while exact solutions have been calculated for velocity profile and pressure gradient. The solution depends on Brownian motion number N (b) , thermophoresis number N (t) , local temperature Grashof number B (r) and local nanoparticle Grashof number G (r) . The effects of various emerging parameters are investigated for five different peristaltic waves. It is observed that the pressure rise decreases with the increase in thermophoresis number N (t) . Increase in the Brownian motion parameter N (b) and the thermophoresis parameter N (t) temperature profile increases. Streamlines have been plotted at the end of the article.
