Abstract
⺠In this paper Lattice Boltzmann simulation of natural convection in an open enclosure which subjugated to water/copper nanofluid has been investigated. ⺠Calculations perform for Rayleigh numbers (Ra = 104-106), volume fractions of nanoparticles (0â¤Ïâ¤0.05) and open enclosure aspect ratios (0.5â¤Aâ¤2). ⺠The decrease in aspect ratio and Rayleigh number enhancement resulted in augmentation of heat transfer. ⺠Growth of naoparticles volume fraction increases the heat transfer at various aspect ratios and Rayleigh numbers.
