【摘要】 在流化床冷态实验中借助现代技术手段──多媒体计算机进行了图像测量.通过图像处理得到了床料波动时间序列,经过对该时间序列的混沌分析表明,本文所研究的流化床系统是一个非线性的系统,由图像测量得出的床料波动时间序列富含气固两相流系统的多变量动力学状态信息.其中流化数对吸引子的影响较小;静止床层高度越低,床内动力状态越趋于混沌;颗粒粗细对吸引子的影响是颗粒越细,床层越容易混沌.

【Abstract】 In this paper the imaging information of FBC is studied with chaotic theory. The resuls reveal that the imaging information contains rich information of kinetic status of FBC, The FBC is a non-linear system which is chaotic. The thetor consthected from Anaging information can be used to distinguish the behavior patens of different regimes such as fluidized air rate, bed materials height and particles size. The fluidized air rate has little effect to the shape of attractor. The effect of the bed materials height is that more small it is, more chaotic the FBC is. The effect of the prtcles sizes that moresmall it is, the FBC tends to chaotic also.
