| Summary: | 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. |
