RT Journal Article ID 7e8a3ae734352c9d A1 Xu, Feng A1 Patterson, John C. A1 Lei, Chengwang T1 OBSERVATION AND SIMULATION OF THE DOUBLE LAYER STRUCTURE OF THE THERMAL BOUNDARY LAYER IN A SIDE-HEATED CAVITY JF Journal of Flow Visualization and Image Processing JO JFV YR 2006 FD 2006-11-12 VO 13 IS 3 SP 287 OP 297 AB The double layer structure of the thermal boundary layer in a side-heated cavity is investigated numerically and experimentally. Through comparing the flow visualizations with the numerical results, the mechanisms of the transition of the thermal boundary layer are discussed. The numerical results demonstrate that an upward thermal tongue leads to the double layer structure of the thermal boundary layer in the quasi-steady stage, which is observed in shadowgraph images.
