The glottal airflow is modeled as a two-dimensional incompressible flow driven by a constant subglottal pressure, and the vocal folds are modeled as a pair of three-layered, two-dimensional, viscoelastic structures. Both the fluid dynamics and viscoelasticity are solved on fixed Cartesian grids using a sharp-interface immersed boundary method. It is found that the vibration mode and frequency of the vocal fold model are associated with the eigenmodes of the structures, and that the transition of the vibration mode takes place during onset of the sustained vibration. The computed glottal waveforms of the volume flux, velocity, and pressure are reasonably realistic. The glottal flow features an unsteady jet whose direction is deflected by the large-scale vortices in the supraglottal region. A detailed analysis of the flow and vocal fold vibrations is conducted in order to gain insights into the biomechanics of phonation.<\/jats:p>","DOI":"10.1121\/1.3158942","type":"journal-article","created":{"date-parts":[[2009,7,28]],"date-time":"2009-07-28T22:18:23Z","timestamp":1248819503000},"page":"816-824","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":58,"title":["Analysis of flow-structure interaction in the larynx during phonation using an immersed-boundary method"],"prefix":"10.1121","volume":"126","author":[{"given":"Haoxiang","family":"Luo","sequence":"first","affiliation":[{"name":"Vanderbilt University Department of Mechanical Engineering, , 2301 Vanderbilt Place, Nashville, Tennessee 37235"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajat","family":"Mittal","sequence":"additional","affiliation":[{"name":"George Washington University Department of Mechanical and Aerospace Engineering, , Washington, DC 20052"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven A.","family":"Bielamowicz","sequence":"additional","affiliation":[{"name":"George Washington University Division of Otolaryngology, , Washington, DC 20052"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023073102145606400_c1","doi-asserted-by":"publisher","first-page":"2270","DOI":"10.1121\/1.1699392","article-title":"Nonlinear dynamic analysis of voices before and after surgical excision of vocal polyps","volume":"115","year":"2004","journal-title":"J.
