Characteristics of temperature oscillation inthermocapillary convection in rectangular pool

  • 摘要: 研究了矩形液池中由于两端温差引起的热毛细对流的温度振荡临界条件.在实验室中,设计了一个高分辨率的温度测量系统,用于实时观测并记录流体的温度.该系统主要由热电偶温度传感器、纳伏表和数据采集电脑3部分组成.得到了各种实验条件下温度振荡的临界条件,并且讨论了它与Prandtl数和Bond数之间的关系.利用flow3d软件数值模拟了微重力条件下的热毛细对流,发现了一种由于自由面变形和液层流场相互作用导致的晃荡的现象.
