Heat and Mass transfer analysis of the peristaltic driven flow of nanofluid in an asymmetric channel

Abstract

In this study, we have investigated the analysis of heat and mass transfers on the peristaltic motion of (Al2O3/H2O)and (Al2O3/C2H6O2)nanofluid in an asymmetric channel. The governing equation of fluid flow is modulated under the consideration of an externally applied magnetic field. Under the consideration of the lubrication theory, lengthy governing equations are abridged. The reduced coupled non-linear partial differential equations are solved analytically. The results of (Al2O3/H2O)and (Al2O3/C2H6O2)nanofluids velocity profile, temperature, concentrations are illustrated by computational mathematical softwares Matlab and the streamlines of trapping phenomenon is illustrated by Mathemtica. All the results are clearly discussed through the plotted graphs. It is noticed that, the concentration decreases when Brownian diffusion parameter and chemical reaction parameter increases, but the opposite effect is concluded for enhancing of thermophoresis parameter.
