Abstract：

The　coalescence　behaviors　of　two　neutral　droplets　suspended　in　silicone　oil　under　the　alternating　current　(AC)　and　pulsed　direct　current　(DC)　electric　fields　are　investigated　by　experiments　and　numerical　simulations.　The　distribution　evolutions　of　electric　force　and　velocity　field　during　the　droplet　coalescence　under　the　AC　and　pulsed　DC　electric　fields　are　analyzed.　The　relationship　between　electric　field　excitation　and　droplet　interface　response　is　illustrated.　The　equivalent　response　mechanism　of　droplets　under　the　high-frequency　AC　and　pulsed　DC　electric　fields　and　under　the　DC　electric　fields　is　revealed.　The　relationship　of　droplet　dynamic　behaviors　under　the　DC　electric　field　and　under　the　AC　and　pulsed　DC　electric　fields　are　established.　The　critical　electric　field　frequencies　above　which　the　shortest　distance　curves　no　longer　change　under　the　AC　and　pulsed　DC　electric　fields　are　obtained.　These　new　findings　are　significant　for　the　optimization　of　electrostatic　coalescence.　©　2021　Elsevier　Ltd
