Thermal case study of nanofluid flow in partially heated rectangular enclosure rooted with sinusoidal heated rods and inclined magnetic field

Abstract

The natural convection nanofluid flow in a partially heated rectangular enclosure is studied numerically. For better novelty, an inclined magnetic field is carried externally. The wavy heated rods are installed at both the bottom and upper walls of an enclosure. Copper-Oxide (CuO) nanoparticles are suspended in the flow field. The nanofluid flow is mathematically formulated in terms of differential equations. The finite element method is used to examine the flow field in a partially heated rectangular enclosure. The flow-affecting parameters are Hartmann number and angle of inclination. The quantity of interest includes horizontal velocity, vertical velocity, and Nusselt number. The outcomes are shared in terms of contour and line plots. It is observed that for increasing values of the Hartmann number, the Nusselt number at the upper heated sinusoidal rod shows a higher magnitude in comparison with a lower heated corrugated rod.
