| Abstract: | The drop formation in micro-channel under the influence of electric field was analyzed through numerical simulation.The CLSVOF coupled model and MHD model were used to investigate the evolution of droplet morphology and the distribution of velocity and pressure in different stages of droplet formation.This research result contributed to promoting the understanding and control of multiphase flow in microsystems,and eventually providing theoretical basis and technical support for the design and optimization of micro-reactors. |
