Peristaltic flow of MHD Jeffery nanofluid in curved channel with convective boundary conditions: a numerical study

摘要

The purpose of present work is to investigate the magnetohydrodynamic aspect in peristalsis of Jeffery nanofluid in curved channel. Heat transfer analysis comprised thermal radiation while the mass transfer has been discussed in terms of thermophoresis, Brownian motion and chemical reaction. With reference to blood flow in circular compliant arteries the curved channel boundaries are considered flexible. Moreover flow equations are formulated under more general approach of convective boundary conditions. Inertial effects have been neglected by small Reynolds number and large wavelength considerations. The detailed physical interpretation of velocity, temperature, nanoparticles mass transfer and heat transfer rate has been presented toward different emerging parameters. The recorded results indicate non-symmetric behavior of velocity in curved channel. Further Brownian motion and thermophoresis impacts on the temperature and mass transfer of nanoparticles are found contradictory. In addition magnetic field causes reduction in velocity and temperature of fluid.
