| Abstract: | A new fuzzy measuring model for the average particle size in fluidized bed is described in this paper. The measurement was made on a gas-solid fluidized bed in our laboratory.The pressure fluctuation signals were obtained and analyzed through power spectrum density.The relation of the particle size to pressure fluctuation and other parameters was studied by using fuzzy set theory. |
