Specifically, an idealized larynx model is constructed and ten cases of three-dimensional (3D) fluid\u2013structure interaction (FSI) simulations are performed. The flow data are then extracted to train the 1D flow model using a sparse identification approach for nonlinear dynamical systems. As a result of training, we obtain the analytical expressions for the entrance effect and pressure loss in the glottis, which are then incorporated in the flow model to conveniently handle different glottal shapes due to vocal fold vibration. We apply the enhanced 1D flow model in the FSI simulation of both idealized vocal fold geometries and subject-specific anatomical geometries reconstructed from the magnetic resonance imaging images of rabbits' larynges. The 1D flow model is evaluated in both of these setups and shown to have robust performance. Therefore, it provides a fast simulation tool that is superior to the previous 1D models.<\/jats:p>","DOI":"10.1121\/10.0003561","type":"journal-article","created":{"date-parts":[[2021,3,11]],"date-time":"2021-03-11T12:08:13Z","timestamp":1615464493000},"page":"1712-1723","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":10,"title":["A one-dimensional flow model enhanced by machine learning for simulation of vocal fold vibration"],"prefix":"10.1121","volume":"149","author":[{"given":"Zheng","family":"Li","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Vanderbilt University 1 , 2301 Vanderbilt Place, Nashville, Tennessee 37235-1592, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ye","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Vanderbilt University 1 , 2301 Vanderbilt Place, Nashville, Tennessee 37235-1592, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siyuan","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Vanderbilt University 1 , 2301 Vanderbilt Place, Nashville, Tennessee 37235-1592, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernard","family":"Rousseau","sequence":"additional","affiliation":[{"name":"Department of Communication Science and Disorders, University of Pittsburgh 2 , Pittsburgh, Pennsylvania 15213, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1984-1040","authenticated-orcid":false,"given":"Haoxiang","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Vanderbilt University 1 , 2301 Vanderbilt Place, Nashville, Tennessee 37235-1592, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2021,3,11]]},"reference":[{"key":"2023080410191530600_c1","doi-asserted-by":"publisher","first-page":"19","DOI":"10.3389\/fphys.2011.00019","article-title":"Toward a simulation-based tool for the treatment of vocal fold paralysis","volume":"2","year":"2011","journal-title":"Front.
