| 摘 要： | 用分形的特征参数--关联维数来表征油气水多相流流动的分形性质.对水平管内油气水多相流流动的瞬态压差信号序列运用相空间重构法进行处理,计算出各种流型的压差信号的关联维数.分析结果表明,各种流型的信号序列在重构的伪相空间中具有不同的关联维数,反映了各个流型的动力学形成机制的不同,所以关联维数可用于多相流流型的识别.实验结果证明,这种采用分形理论对多相流流型进行识别的新颖方法是十分有效的.

| Abstract: | Oil-gas-water multiphase flow exhibits
fractal characteristics,the dimension of which can be correlated. Instantaneous
differential pressure signals for horizontal flow are processed by reconstructing the
phase space. Correlation dimensions are calculated, they show that different results are
found for different flow regimes and hence for the reconstruction of pesudo-phase
space.The corresponding correlation dimensions can be used to identify flow regime of
oil-gas-water multiphase flow. |

| Keywords: | fractal correlation dimension multiphase flow flow regime |
