| 摘 要： | 应用高速数字摄像与图形分析技术,在水平管中对弹状流长气泡区液膜流动的连续波特征进行了实验研究,理论分析表明弹状流长气泡区的液膜流是传播速度等于长气泡平移速度的连续波,提出了液膜厚度的控制方程,对液膜厚度的计算结果与测量结果相符合。得到弹状流中存在连续波的重要结论,揭示了稳定弹状流具有波动特性的物理本质。

| Abstract: | Visualized observation on the wave feature in the horizontal slug flow was made with highspeed digital camera. It was found that the liquid film flow in the elongated bubble region of slug flow behaves as a continuity wave. Theoretical analysis was carried out and it reveals that the liquid film flow is a continuity wave with celerity the same as the translational velocity of the elongated bubble. The control equation for the liquid film height in the elongated bubble region was derived. The results predicted by the equation fit well with the observed data. A new conclusion was obtained as that slug flow has continuity wave in it, explaining why the stable slug flow has wave characterization. |
