| 1. | Another measure of holdup is the k factor used by bankoff in connection with the bubble flow pattern in gas-liquid flow . 滞留现象的另一个度量是Bankoff在气-液流动的泡状流型中所采用的因数K。 |
| 2. | Gas - liquid two - phase dispersal bubble flow model of horizontal borehole 证据理论的气液两相流流型识别方法 |
| 3. | Flow patterns of oil - water - gas three - phase downward flow and transition from bubble flow to slug flow 油水气三相流的流型及泡状流向弹状流的转变 |
| 4. | Another measure of holdup is the k factor used by bankoff in connection with the bubble flow pattern in gas - liquid flow 滞留现象的另一个度量是bankoff在气-液流动的泡状流型中所采用的因数k 。 |
| 5. | And also we study the bubble flow behavior of the bubbling fluidized bed . the single bubble and continuous bubble formation , rise , break and coalesce characteristics are studied separately and compared with the experimental data . it shows good consistency 随后研究了鼓泡床内的气泡运动变化规律,分别模拟了单个气泡和连续气泡的生成、生长、破裂以及合并等的行为特性并且和实验数据进行了对照,取得了较好的结果。 |
| 6. | Based on these models , the differential pressure fluctuation signals of gas - liquid two - phase flow under different flow regimes in various diameter pipelines are analyzed . experimental results show that the autoregressive orders of bubble flow and annular flow are bigger than that of slug flow 对不同管径不同流型下的差压波动信号进行了建模,在此基础上分析得出:弹状流流型下arma模型的阶数n最小,泡状流和环状流流型下的arma模型阶数n较大。 |
| 7. | At first , bubble flow image is acquired using laser and incandescence lamp respectively as light source and using ccd . according to different optics - dispersion character , threshold segmentation method is proposed to identify gas from the gas - water flow , which make steadfast base for further calculate void fraction . the precision of threshold directly affect the calculate precision of void fraction 文中分别采用激光片光源和影视灯照明,采用逐行扫描数字ccd摄像机获取气泡的流动图像;根据气泡和水对光的反射特性不同,提出采用阈值法识别图像中的气泡和水,从而为进一步计算掺气浓度打下坚实的基础。 |
