Influences of Chemical Reaction and Convective Boundary Conditions on the Peristaltic Transport of MHD Jeffery Nanofluids

摘要

In this study, the peristaltic transport of a MHD Jeffery nanofluid in a tapered asymmetric channel is focused. The channel walls flaunt convective boundary conditions. Chemical reaction, thermal radiation and heat source/sink parameters effects on the temperature equation are retained. Combinations of asymmetric and non-uniform channels are named as tapered asymmetric channel which may be identified in uterus and cervical areas. Mathematical analysis is executed to long wavelength and low Reynolds number assumptions. The considered flow analysis contains Brownian motion and thermophoretic diffusion. The analytical expressions for nanoparticle temperature and concentration fields are computed by using homotopy perturbation method (HPM). The nanoparticles temperature distribution is compared with numerical solution and the results are found to be in good agreement. The graphical results of the problem under discussion are also being contributed under consideration to insure the behavior of various physical parameters. It is also viewed that the pumping rate decreases with an increase of chemical reaction parameter and non-uniform channel in the peristaltic pumping and free pumping regions.
