Influence of magnetic field on natural convection and entropy generation in Cu–water nanofluid-filled cavity with wavy surfaces

This paper investigates the influence of a magnetic field on the natural convection heat transfer and entropy generation of Cu–water nanofluid in a cavity with complex-wavy surfaces. The study examines the effects of the Hartmann number, Rayleigh number, Eckert number, nanoparticle volume fraction, and wavy-wall geometry parameters on the Nusselt number, entropy generation and Bejan number. The results show that at higher values of the Rayleigh...
