Cross Diffusion Impacts on Hydromagnetic Radiative Peristaltic Carreau-Casson Nanofluids Flow in an Irregular Channel

Abstract

The hydromagnetic peristaltic motion of Carreau and Casson nanofluids flow in an irregular channel in the presence of diffusion thermo (Soret) and thermo diffusion (Dufour) impacts has been examined. The effect of thermal radiation is incorporated in the energy equation and velocity slip included in the boundary conditions. The dimensionless governing equations for the flow, fluid temperature and nanoparticle concentration are acquired for the suppositions of low Reynolds number and large wavelength. Resulting flow problem has been solved numerically. Outcome of emerging sundry variables on these three flow profiles are graphically analyzed. Axial velocity enhances near the walls of the irregular channel to the mounting values of Hartmann number where as the velocity declines in the central part of the irregular channel. Temperature magnifies considerably with the boosting values of Dufour number. Impact of Soret number decays concentration. Also, a comparative study is made for the numerical results of axial velocity with the existing reports. In addition the numerical results of the friction factor, energy and mass transfer rates for both Carreau and Casson nanofluids are analyzed through the tables.
