摘要: 针对均匀电场作用下两相系统中的单个离散相周围电场分布情况,建立了数学模型.在建模过程中,考虑了离散相的存在对电场分布的影响.通过求解电场控制方程,得到了均匀电场作用下离散相周围及其内部的电势及电场分布的数值解,并理论验证了该数值解的准确性.

Abstract: A mathematical model was established to predict the electric field distribution around a single discrete phase in two-phase system applied uniform electric field. The difference of the dielectric permittivities between the discrete phase and dielectric liquid was considered.The equipotential lines and electric field strength around the single discrete phase were obtained by solving the governing equation for electric field. The numerical simulation results presented are in good agreement with theoretical analysis.

Key words: electrohydrodynamics, numerical simulation, electric field distribution, discrete phase
