Abstract :
Because of the complexity and randomness of the gas-solid two-phase flow, it is still hard to fully understand the dynamic behavior of the flow. The electrostatic signal contains rich information of the particulate flow. Multiscale entropy (MSE) analysis of electrostatic fluctuation signal was conducted in this paper. The electrostatic signals were obtained from the horizontal pipeline in dilute pneumatic conveying system. The influence of sequence length on MSE of electrostatic signal was analyzed at first. Then the influence of solids concentration and superficial air velocity on MSE was shown, which reflects that it is helpful for understanding of the dynamics of two phase flow.
