导电微粒在稍不均匀场中荷电运动的离散元算法开发
Development of DEM for Conductive Particulate Charge and Motion Under Slightly Non-uniform Electrical Field
摘要
Abstract
The study of charge motion characteristic of conductive particle is of great significance for the treatment of conductive particle defect in gas insulated switchgear.At present the method of studying charge motion of particle with numerical simulation is less and is only limited to Eulerian simulation.In view of the above problems,a kind of new strategy to calculate the motion of particles based on discrete element method is proposed.The correctness of the algorithm is verified by comparing the results of experiments and calculation data,the motions of multiple spherical particles/dust and linear particles have been successfully simulated as well.The application advantage of the algo-rithm and the further development value and potential are proved.关键词
