Thermophoresis particle deposition analysis for nonlinear thermally developed flow of Magneto-Walter's B nanofluid with buoyancy forces

In this study, we have discussed thermophoresis particle deposition effects under the action of both pressure and buoyant forces flow of magneto-Walter's B nanofluid induced by a stretched surface. The Buongiorno nanofluid model is employed to analyze the dynamic impact of thermophoretic dispersion and Brownian motion. The effects of chemical reaction, Joule heating and non-linear radiation relations are also incorporated. The analysis has been performed in view of solutal and heat convective boundary constraints. The analytical technique namely homotopy analysis scheme followed to solve the resulting non-linear governing equations. The behavior of velocity, temperature and concentration profiles are observed graphically. The physical consequences for all physical parameters are justified. It is noted that heat thermal Biot number, thermophoretic constant and viscoelastic parameter increases the nanofluid temperature and concentration. A decaying concentration profile is noted for Schmidt number. (C) 2020 The Authors. Published by Elsevier B.V. on behalf of Faculty of Engineering, Alexandria University.

Automated summary

This study discusses the thermophoresis particle deposition effects of magneto-Walter's B nanofluid induced by a stretched surface under the action of pressure and buoyant forces, utilizing the Buongiorno nanofluid model. The analysis incorporates chemical reaction, Joule heating, and non-linear radiation relations, with the results showing that the heat thermal Biot number, thermophoretic constant, and viscoelastic parameter increase the nanofluid temperature and concentration while a decaying concentration profile is observed for the Schmidt number.
