The assumption of quasi-one-dimensional flow through a glottis with fixed length is analyzed for different cross-section shapes: Circle, rectangle, ellipse, and circular segment. A simplified flow model is formulated which accounts for kinetic losses, viscosity, and cross-section shape. It is seen that the cross-section shape cannot be neglected since it alters boundary layer development and hence the viscous contribution to the pressure drop across the glottis. The commonly applied quasi-one-dimensional flow model is shown to be inaccurate, indicating the potential benefit of taking into account the cross-section shape.<\/jats:p>","DOI":"10.1121\/1.4813397","type":"journal-article","created":{"date-parts":[[2013,8,2]],"date-time":"2013-08-02T23:09:48Z","timestamp":1375484988000},"page":"909-912","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["The influence of glottal cross-section shape on theoretical flow models"],"prefix":"10.1121","volume":"134","author":[{"given":"Bo","family":"Wu","sequence":"first","affiliation":[{"name":"GIPSA-Lab, UMR CNRS 5216, Grenoble University , F-38031 Grenoble Cedex 1, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annemie","family":"Van Hirtum","sequence":"additional","affiliation":[{"name":"GIPSA-Lab, UMR CNRS 5216, Grenoble University , F-38031 Grenoble Cedex 1, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xavier","family":"Pelorson","sequence":"additional","affiliation":[{"name":"GIPSA-Lab, UMR CNRS 5216, Grenoble University , F-38031 Grenoble Cedex 1, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyu","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Mathematics and Statistics, University of Glasgow , Glasgow G12 8QW, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023080301281793900_c1","doi-asserted-by":"crossref","first-page":"1233","DOI":"10.1002\/j.1538-7305.1972.tb02651.x","article-title":"Synthesis of voiced sounds from a two-mass model of the vocal cords","volume":"51","year":"1972","journal-title":"Bell Syst.
