Natural convection flow in inclined air-filled enclosures of small and moderate aspect ratio
Abstract
Natural convection in rectangular inclined air-filled enclosures was studied by means of flow visualization and laser Doppler anemometry for Rayleigh numbers between 10,000 and 250,000. The angle of inclination was varied between 0 deg and 90 deg, while the aspect ratio was varied between 0.25 and 7. Transition curves were determined for transition from stationary to nonstationary flow and for two-dimensional to three-dimensional flow. Velocity profiles were measured to determine the influence of the aspect ratio and the Rayleigh number on convection.
