摘要：

A fractal approach was adopted to describe the behaviour of the pressure fluctuations in a bubble column. The values of the so-called Hurst exponent computed from the rescaled range analysis were used to distinguish between the basic hydrodynamic regimes. The experimental data were compared with the simulated sequences of the fractional Brownian motion.
