摘要：

Fluidized beds display a degree of structure which it is vital to understand in any design and scale-up of equipment. This paper is on the employment of chaos theory to describe this structure. The measuring technique of electrical capacitance tomography is used to determine the local porosity of a gas-solids fluidized bed and to monitor its fluctuation with time; These raw data are translated into invariants characteristic of the structure mentioned, such as the Kolmogorov entropy. Initial measurements have shown a strong variation in these chaotic invariants with bed position and operational parameters. First results are compared with earlier data from pressure measurements.
