CHAOS STUDY ON TIME SEQUENCE OF DIFFERENTIAL PRESSURE FOR GAS-SOLID TWO-PHASE FLOW

XIE Fei, DING Yan-jun, WU Zhan-song (Qinghua University, Beijing 100084, PRC)  
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.
