| 摘 要： | 为了有效调控中尺度气泡的行为,在纯水中通过添加不同浓度的3种表面活性剂实验研究了气泡上升过程中的形状与速度的变化.在一个方截面柱形容器内生成了4种中尺度气泡,再利用高速摄影仪记录了气泡的瞬时运动过程,通过图像处理软件分析了气泡的形状和速度.结果表明,由于Marangoni效应,适量的表面活性剂可以有效抑制中尺度气泡的变...

| Abstract: | Experiments were conducted on the variations of shape and velocity of single bubbles during rising in three types of surfactant solutions with different concentration in order to effectively modulate the behavior of meso-scale bubbles in bubbly flow.Single bubbles with the size of 1.3-6 mm were generated in a square glass column,and the instantaneous motion of single bubbles was recorded using a high-speed camera.Then bubble shape and velocity were determined from the recorded frames using the image analysi... |
