摘要
利用混沌理论中的特征量——关联维数和Kolmogorov熵对文丘里管内的气固两相流差压时间序列数据进行分析,从特征量的变化研究了系统的混沌特性,得到了相关维数和Kolmogorov熵与差压的定性关系,研究从另一个角度证明了文丘里法测量煤粉流量的合理性。
The time sequence data of differential pressure for gas - solid two - phase flow of the Venturi tube have been analysed by using the correlated dimensions and the Kolmogorov entropy, i.e. the eigenwerts in chaos theory, and the chaos nature of the system being studied from variation of the said eigenwerts, obtaining the qualitatigve relationship between the differential pressure and correlated dimensions, as well as the relationship between the differential pressure and Kolmogorov entropy, verifying the reasonability of measuring mass flow rate for pulverized coal from other view point.
