Heat transfer enhancement in natural convection using water based Fe3O4 nanofluid inside a square cavity

摘要: Natural convection heat transfer has many applications, especially in the field of solar thermal electronic cooling etc., Heat enhancement techniques natural deals essentially with addition fins various configuration. Since introduction nanofluids by Choi et al [1], continue to be considered as one sought after options enhancement. This is due excellent improvement characteristics nanosized solid particles into base fluids such water, ethylene glycol In present study, an effort made study inside a square cavity when water seeded magnetic Fe 3O4 nanoparticles using numerical experiments. The volume fractions analysis range from 0.1% 0.6%. It observed that less than 10% for and 0.3% Rayleigh numbers considered.
