A fully coupled numerical simulation of the three-dimensional electrohydrodynamic jet flow is used here since non-symmetric effects govern most of their EHD regimes. By applying considerable electric capillary numbers (CaE&amp;gt;0.25), we capture radial instabilities that until now no other numerical simulation was able to present. A comparison against previous two-dimensional axis-symmetric and validation with experimental studies of the Taylor cone jet is initially done. An exciting gain in accuracy was obtained, having an error of around 1.101% on the morphology against experimental results. Moreover, our numerical model takes into consideration the contact angle between the surface of the nozzle and the liquid, which is shown to be a very important variable for improved accuracy in the morphologic shape of the Taylor cone. Moreover, the three-dimensional structures and flow dynamics, under different electric capillary numbers, and their connection to the instabilities of the jet are studied. We present a novel visualization of the formation of droplet generation with the receded Taylor cone and the whipping dynamics.<\/jats:p>","DOI":"10.1063\/5.0151109","type":"journal-article","created":{"date-parts":[[2023,5,15]],"date-time":"2023-05-15T11:22:41Z","timestamp":1684149761000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":25,"title":["Dynamics of three-dimensional electrohydrodynamic instabilities on Taylor cone jets using a numerical approach"],"prefix":"10.1063","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4176-1178","authenticated-orcid":false,"given":"S\u00edlvio","family":"C\u00e2ndido","sequence":"first","affiliation":[{"name":"Department of Electromechanical Engineering, C-MAST, University of Beira Interior , 6200-001 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7019-3766","authenticated-orcid":false,"given":"Jos\u00e9 C.","family":"P\u00e1scoa","sequence":"additional","affiliation":[{"name":"Department of Electromechanical Engineering, C-MAST, University of Beira Interior , 6200-001 Covilh\u00e3, Portugal"}]}],"member":"317","published-online":{"date-parts":[[2023,5,15]]},"reference":[{"key":"2023102715241697900_c1","doi-asserted-by":"publisher","first-page":"3305","DOI":"10.1515\/ntrev-2022-0498","article-title":"Electrohydrodynamic printing for demanding devices: A review of processing and applications","volume":"11","year":"2022","journal-title":"Nanotechnol.
