摘要：
Based on the idea of element deformation, a numerical calculation model on droplet deformation in the electric field was established, from the element conservation equation. The model was coupled with the dipole model, and a calculation method on droplet coalescence was also proposed. Based on the established model and calculation method, a numerical calculation program was compiled the deformation and coalescence of droplets under several parameters were simulated. Results show that the prediction of droplet deformation is in good agreement with the experiment, the prediction of droplet coalescence is roughly consistent with the experiment and the predicted coalescence time is slightly lower than the experimental value. If the modeling accuracy of element resistance and the discrete accuracy of element are further improved, the model will have better applicability. The simulation results also show that the present model can be also used to predict the oblate deformation of droplets. The work has an active role for the theoretical analysis and numerical simulation of droplet deformation. © 2021, Zhejiang University Press. All right reserved.
