New Forced Convection Flow of Nanofluid Within a Partially Filled Porous~Straight Channel

This study specifically examines how the movement and dispersion of nanoparticles affect heat transfer in a linear channel that contains a partially porous medium. The existing body of literature is lacking a comprehensive understanding of the convective heat transfer of nanofluids in porous channels. This presents an open research topic that demands further investigation. The porous channel is modelled using Finite Element Method (FEM) for steady flow. The assumption of thermal equilibrium model is made between the solid phases and nanofluid. The non-uniform distribution of nanoparticles within the channel is postulated. Consequently, the equation for the distribution of volume fraction is interdependent with the governing equations. A comprehensive analysis has been conducted on the impact of various parameters, including Darcy number and Reynold number. The findings indicate that the relationship between the Reynolds number and the Nusselt number is direct, meaning that any increase in the Reynolds number results in an increase in the Nusselt number. Moreover, any increment in the Darcy number leads to an increment in the Nusselt number.
