摘要：

The effects of operating parameters on the basic statistical characteristics of pressure fluctuations were studied for different measurement configurations in a bubble column of diameter 0.292 m. Different sources of the pressure signal were identified using cross-spectral analysis. A simple parametric method was proposed for on-line flow pattern identification based on the optimal order of the autoregressive model.
