Abstract:The study of natural convection in enclosures has attracted the attention of numerous researchers over the past decades due to its applications in many practical engineering problems. Some examples include air conditioning and ventilation systems, electronic cooling devices, heat exchangers and thermal storage. In the present work an experimental investigation of natural convection developed in an air filled cube of side H=0.35m is conducted using Particle Image Velocimetry (PIV) to measure the velocity field within the cavity and visualize the dominant flow structures. The low turbulence Rayleigh number regime 5.08E7
