摘要：

A dual probe has been developed for the measurement of bubble behaviour and pressure fluctuations in a fluidized bed. Data obtained, with relatively good precision by the dual signals included bubble sizes and bubble rise velocity; particle concentration around the bubble; pressure gradient within the bubble; the wave propagation mode and the relationship between signals by means of auto- and cross-correlation. Based on the mode of wave propagation, the components of the pressure fluctuations can be analysed. Some results from the present study show the differences compared with those in the literature. © 1990.
