Effect of Fins on the Transition to Oscillating Laminar Natural Convection in an Enclosure
Ohio State University, Mechanical and Aerospace Engineering, USA
Flow characteristics and evolution of heat transfer are investigated numerically within a differentially heated square cavity in the 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 fins positioned at different locations.
