Heat transfer augmentation in water-based TiO_2 nanoparticles through a converging/diverging channel by considering Darcy-Forchheimer porosity

K. Ganesh Kumar, S.A. Shehzad, T. Ambreen, and M.I. Anwar


This article executes MHD heat transport augmentation in aqueous based  nanoparticles fluid flow over convergent/divergent channel. Joule heating, magnetic field and Darcy-Forchheimer effects are explained for concentration and temperature distributions. Darcy-Forchheimer theory is utilized to explore the impact of porous medium. The system of partial differential expressions is transformed into ordinary ones and evaluated numerically by implementing RKF-45 scheme. Expressions for velocity and temperature profile are derived and plotted under the assumption of flow parameter. Influence of various parameters on heat transfer rates and surface drag force are discussed with the help of table and plots.
