Two-dimensional vocal folds are simulated with material properties chosen to result in self-oscillation and volume flows in physiological frequency ranges. Properties of the glottal flow field, including vorticity, are studied in conjunction with the dynamic vocal fold motion. The results of using the PIB method to model self-oscillating vocal folds for the case of 8cm\u2008H2O as the transglottal pressure gradient are described. The volume flow at 8cm\u2008H2O, the transglottal pressure, and vortex dynamics associated with the self-oscillating model are shown. Volume flow is also given for 2, 4, and 12cm\u2008H2O, illustrating the robustness of the model to a range of transglottal pressures. The results indicate that the PIB method applied to modeling phonation has good potential for the study of the interdependence of aerodynamics and vocal fold motion.<\/jats:p>","DOI":"10.1121\/1.2354069","type":"journal-article","created":{"date-parts":[[2006,11,16]],"date-time":"2006-11-16T17:22:13Z","timestamp":1163697733000},"page":"2859-2871","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":26,"title":["Modeling coupled aerodynamics and vocal fold dynamics using immersed boundary methods"],"prefix":"10.1121","volume":"120","author":[{"given":"Comer","family":"Duncan","sequence":"first","affiliation":[{"name":"Bowling Green State University Department of Physics and Astronomy, , Bowling Green, Ohio 43403"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangnian","family":"Zhai","sequence":"additional","affiliation":[{"name":"Bowling Green State University Department of Physics and Astronomy, , Bowling Green, Ohio 43403"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald","family":"Scherer","sequence":"additional","affiliation":[{"name":"Bowling Green State University Department of Communication Disorders, , Bowling Green, Ohio 43403"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"issue":"6","key":"2023080123421019200_c1","first-page":"2003","article-title":"A finite-element model of vocal-fold vibration","volume":"108","year":"2000","journal-title":"J.
