| 摘 要： | 为明晰电场对两相系统中离散相的作用,本文针对均匀电场作用下两相系统中的单个离散相的行为进行了可视化试验研究及数值模拟。通过建立电场数学模型。得到了均匀电场作用下两相系统的电场分布;运用电应力表面积分的方法求得了离散相所受的电场力。并于试验中观察了不同粒径的离散相在电场作用下的运动情况,其试验结果与数值计算结果基本吻合。

| Abstract: | In order to clarify the effects of the electric field on the discrete phase in a two-phase system, the numerical and experimental studies of a single discrete applied a uniform electric system have been made in this paper. By establishing the mathematical model of electric field, the electric field distribution of the two-phase system was obtained The electric body force acting on the discrete phase was determined using the method of integration at the sphere surface. In experimental studies, the movements of the dielectric sphere with different diameters were visualized under a uniform electric field. The numerical and experimental results showed generally good agreements. |
