Influence of Heat and Mass Transfer on Nanofluid Peristaltic Motion Through a Curved Asymmetric Channel

In this present research article, a new mathematical model is established for pressure-driven nanofluid flow caused by the rhythmic oscillatory movement with phase difference and amplitudes of the walls of a curved conduit in the existence of mass/energy transfer. The developed model simulates more realistically peristaltically mediated fluid motion in different physiological conduits. The governing equations of the suggested problem are shortened and made relatively simple after the absence of inertial effects by utilizing high wavelength approximations. The analytical expressions of nanoparticle temperature and volume fraction are derived by Homotopy Perturbation method (HPM). Finally, the exact expression for the trapping phenomena is also derived. The consequences of numerous pertinent parameters on the flow characteristic variables such as nanofluid velocity, temperature, nanoparticle concentration and stream function are explained by sketching the relevant profiles and discussed in depth. The developed mathematical model and its obtained results are validated upon transforming the curved symmetric channel into a straight symmetric channel.
