Abstract

To investigate, a numerical model is suggested to analyse the effect of pliability on the peristaltic flow of a couple- stress fluid with nanoparticles in a cylindrical tube. The expressions for velocity and flux flow rate are determined by using Homotopic Perturbation method, in the process of long wave length and low Reynold’s number approximations. The variation of flux is calculated by Rubinow and Keller, Muzumdar methods. The effects of different criterias on velocity and flux have been discussed. The trapping phenomena is depicted for various parameters.  The flux appears to be increasing with elasticity parameters, couple-stress fluid parameter. The flux also falls as Brownian motion parameter and the Thermophoresis parameter are increased. The obtained results are same when we apply Rubinow and Keller, Muzumdar methods.
