Effect of Fins on the Transition to Oscillating Laminar Natural Convection in an Enclosure

Flow characteristics and evolution of heat transfer are investigated numerically within a differentially heated square cavity in the johnny cash style clothing presence of thin fins which are either insulated or highly conductive and at the base wall temperature.The transition from steady-state to oscillatory and chaotic convection is observed at certain Rayleigh numbers with varying lengths of animed aniflex complete fins positioned at different locations.
