7. Faraday Waves

A droplet of less viscous liquid floating in a bath of a more viscous liquid develops surprising wave-like patterns when the entire system is set into vertical oscillation. Investigate this phenomenon and the parameters relevant to the production of stable patterns. 当整个系统被设定为垂直振荡时,漂浮在粘性较高的液体浴中的液滴会出现令人惊讶的波状图案。研究这一现象以及与产生稳定图案有关的参数。

养成良好的实验记录的习惯(●’◡’●)

课题研究中可以进行记录的内容:

  1. 文献的阅读结果
  2. 课题的开展计划
  3. 实验结果记录的相关链接
  4. 每次课题组会讨论的重点内容

主要研究参数:驱动频率ω、驱动振幅A、深度h、粘度μ、密度ρ、容器尺寸L、 文献阅读的一些收获:1、 When the amplitude of the excitation exceeds a critical value(临界?另一文献描述为加速度a达到临界), standing wave patterns are formed on the surface which oscillate at half the frequency of the drive. 2、For large enough containers(临界?), the surface pattern becomes approximately independent of the boundaries, and line, square, hexagonal, triangular, and 8-fold quasiperiodic patterns have been observed.
