AB - Paper describes a novel method for two-phase gas-solid flow structure  validation in fluidized bed reactors. Investigation is based on application  of stereology techniques. This is an innovative approach in the field of  fluidization phenomena research. Study is focused on the analysis of flow  structure images, obtained with high-speed visualization of the fluidization  process. Fluidization is conducted in transparent narrow channel, where  plastic balls are fluidized by air. Applied stereological analysis is  grounded on the linear method and on the method of random and directed  secants. This enables 2-dimensional image measurement and 3-dimensional  stereological extrapolation. The major result is that for each two-phase  gas-solid flow structure a set of stereological parameters exists. This  enables quantification of the process. It has been found that the observation  of inter-relation of all stereological parameters, during the changing of the  flow structure, can be used for system control. The basic conclusion is that  knowledge about the character of the changes may be used for constant process  adjustment for various two phase systems such as gas-solid or gas-liquid.
