The technique of real-time holographic interferometry is used in the present study to study natural convection in a fully-partitioned air-filled square enclosure. Transient and steady-state temperature distributions in separated subenclosures are visualized for a Rayleigh number between 2.5X105 and 8.4X105 with a centrally-located con- ducting partitions. Steady-state experimental results are found to be in reasonably good agreement with the numerical predictions. Moreover, the experimental observations during the transient one-sided heating processes indicate that the presence of a conducting partition can provide a good buffer against a sudden external disturbance to the enclosure.
