燃烧流化床气泡能量分布模型

Modeling of Energy Distribution of Bubbles of Burning Fluidized Bed

应用瞬态谱分析方法对燃烧流化床声波信号进行了频谱分析，发现气泡能量分布呈Ｇａｍｍａ分布形式，在Ａｒｇｙｒｉｏｕｓ和Ｙｏｓｈｉｄａ等人提出的模型的基础上，发展了燃烧流化床气泡能量分布模型，并通过优化迭代对模型参数进行求解。

The wavelet analysis and Wigner distribution theory are employed to analyze the acoustic signals of a burning fluidized bed.The result shows that the distribution of energy of bubbles in the fluidized bed is coincident with Gamma distribution.Based on the experiment and theory analysis,a more practical model is presented in this paper.
