Peristaltic Flow of Newtonian and Non-Newtonian Fluids


In this thesis, we have investigated the peristaltic flow of Newtonian and non-Newtonian nanofluid flows in a channel, uniform and non-uniform tube. We have modelled and simplified the governing equations of such a fluid under the assumptions of long wave length and low Reynolds number approximation. The momentum equation is solved by utilizing the homotopy perturbation technique for velocity while the exact solutions are computed for temperature and concentration equations. The analysis depicts the impact of different situations such as endoscopic tube, magnetics field, convective boundary conditions and viscous dissipation in the flow of nanofluids induced by pressure gradient. The effects of different governing parameters on velocity and temperature fields are analyzed graphically for peristaltic waves. The physics of the involved parameters and important features of the modeled problems are discussed and analyzed with the help of streamlines and plots for various quantities.
