Research on the relationship between gas-solid two-phase flow pattern and induced charge based on rod electrostatic sensor

In this paper, the amount of induced charge on the electrode of the gas-solid two-phase flow with different flow patterns is studied. The induction mechanism model of rod electrode is established based on Poisson equation and Gauss law,and the flow pattern is divided into slices. To reveal the relationship between the flow pattern and the charge, the simulation is provided. The amount of electrostatic induced charge of diffrrent flow pattern in rod is obtained. The influence of different flow patterns in the pipeline on the amount of induced charge is analyzed, and the correctness of the results is verified by design simulation.
