| Abstract: | Investigations made into a gas-solid-fluidized bed model reactor, aiming at obtaining statements about the spatial and time density distributions within the fluidized bed and the correlation between the state of the turbulent layer and a characteristic measured quantity as well as variation of a physical property of the solid. statisticl evaluation techniques are indispensable, owing to the elementary actions occuring within the fluidized bed reactor and their random nature. Such parameters of the fluidized bed could be determined from a totality of individual measurements for measuring periods of 10 ms per single measurement by use of a miniature measuring probe within the interior of the fluidized bed reactor. This probe consisted of a beta-radition source and a Si-surface barrier-layer detector. |
