Influence of Lorentz Force on Cu-Water Nanoliquid Convective Thermal Transfer in a Porous Lid-Driven Cavity with Uniform and Linearly Heated Boundaries

초록

In this chapter, the magnetohydrodynamic convective flow and heat transport of Cu-water nanofluid filled in a square porous lid-driven cavity has been investigated numerically. Equations governing the fluid flow are non-dimensionalized and transformed into vorticity-stream function equations. Finite difference methods are applied to solve these equations. Computations are valid with existing benchmark results. The numerical simulations have been carried out by considering a thermally linear heated left wall or a uniform heated left wall for a vast range of Darcy number (10-2≤Da≤102), Hartmann number (0≤Ha≤100), Rayleigh number (104≤Ra≤106), and solid volume fraction of range (0.01≤≤0.1). Through a wide range of computational analysis, it has been noticed that an increase in Da increases the flow intensities, and the increase in Ha decreases the flow intensity. Also, it has been observed that secondary circulations are generated, and lesser heat transfer takes place with the linearly heated left boundary. © 2024 selection and editorial matter, Katta Ramesh, Fateh Mebarek-Oudina, and Basma Souayeh; individual chapters, the contributors.
