The rate of coalescence in an electrocoalescer, which governs the residence time, sensitively depends upon the electrostatic conditions as well as the electrodes arrangement. An experimental study of a cylindrical electrocoalescer vessel for two different modes of operation is reported in this work. The design of the coalescer is optimized for the residence time and water separation. To justify the experimental findings and to unravel more physical insights, the single phase electrostatics is simulated using COMSOL Multiphysics software. The volume of the emulsion under the influence of 0.3–1.0 kV/cm electric field, calculated using COMSOL, correlates well with the water separation. Moreover, the simultaneous measurement of current suggests an ordering, that leads to an increase in size of the droplets and settling of drops in the normal operation. On the other hand, chaining and shorting leads to surge in current at high fields and seems to prevent water separation.

控制停留时间的电凝聚器中的聚结速率敏感地取决于静电条件以及电极布置。在这项工作中报道了一种针对两种不同操作方式的圆柱形电按摩器容器的实验研究。聚结器的设计针对停留时间和水分离进行了优化。为了证明实验结果的正确性并揭示更多的物理见解，使用COMSOL Multiphysics软件对单相静电进行了仿真。使用COMSOL计算的0.3–1.0 kV / cm电场影响下的乳液体积与水分离具有良好的相关性。此外，电流的同时测量表明有序，这导致液滴的尺寸增加以及在正常操作中液滴的沉降。
