Physical interpretation of chaotic time series analysis parameters for fluidized beds

PDF Version Also Available for Download.

Description

The Morgantown Energy Technology Center has development programs in a number of fossil energy technologies which use fluidized beds as reactors to carry out combustion, gasification, and desulfurization. The diagnosis of operating problems and control of bed behavior is critical to the efficient performance of these systems. The overall goal of the present work is to develop novel techniques to improve diagnosis and control of these systems. Chaotic time series analysis has recently been used with pressure drop, void fraction, and heat transfer data to characterize fluidized bed dynamics. Unique chaos parameters derived from this analysis can distinguish among various ... continued below

Description

The Morgantown Energy Technology Center has development programs in a number of fossil energy technologies which use fluidized beds as reactors to carry out combustion, gasification, and desulfurization. The diagnosis of operating problems and control of bed behavior is critical to the efficient performance of these systems. The overall goal of the present work is to develop novel techniques to improve diagnosis and control of these systems. Chaotic time series analysis has recently been used with pressure drop, void fraction, and heat transfer data to characterize fluidized bed dynamics. Unique chaos parameters derived from this analysis can distinguish among various fluidization conditions within gas fluidized systems. In this paper, a basis for understanding the physical meaning of several chaotic parameters is developed and illustrated.
