The effect of elasticity on the peristaltic flow of a micropolar fluid containing nanoparticles in a cylindrical tube is investigated using amathematical model. The expressions for velocity and flux flow rate are determined by using Homotopy Perturbation method, underlong wave length and low Reynold’s number approximations. The variation of flux is calculated by Rubinow and Keller, Muzumdarmethods. Different parameters' effects on velocity and flow have been discussed. For various settings, the trapping phenomenon isdemonstrated. The flux increases as the elasticity parameters, micropolar parameter, thermophoresis parameter, and coupling numberincrease. The flux similarly reduces as the Brownian motion parameter is increased. The obtained results are same when we applyRubinow and Keller, Muzumdar methods.
