The result revealed that the critical Marangoni numbers, flow mode and frequency of the 3-D flow of the present ramped Delta-T case are very close to those obtained in the previous works in which Delta-T was kept constant. However, the amplitude of surface temperature oscillations near the second critical point are very small (0.2 K) and its frequency is high (2.5 Hz in 1-T type oscillation). At highly super critical state, the 1-T type oscillatory flow-temperature structures started slow azimuthal motion. This rotation caused a low frequency oscillation of a local surface temperature. At further large Delta-T, there occurred an alternative changes of oscillation mode between 1-T and 2-T, whereas the slow rotation action was maintained. These results seem to explain the experimental observations. Also conducted was a set of Proper Orthogonal Decomposition (POD) analyses for oscillatory flows in liquid bridges of low Pr fluid. POD helped understanding the detailed structures of the 3-D disturbances in a liquid bridge of Pr = 0.01 fluid simulated with a condition of As = 2.0 and Ma = 35.0.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
