| 中文摘要 | In this paper, the time-dependent Be´nard-Marangoni convections of two-layer fluid at the onset of convection are investigated experimentally. The flows are visualized from side with particle image velocimetry (PIV) and structure change of velocity fields near onset of convection are observed while the depth ratio varies in a range. The variation of the critical temperature difference with the depth ratio shows that the "peak depth ratio" is very far from the "balancing depth ratio"; the oscillatory onsets from stationary were obtained in a big gap of depth ratio in which the "peak depth ratio" located. These results don't agree with the predications of the linear stability analysis. |
