We used a rigid model of human airways consisting of asymmetrical bifurcations up to third generation. Velocities in each branch of the bifurcations were measured by two-color laser-Doppler velocimeter. The secondary velocity magnitudes and the deflection of axial velocity were dependent not only on the branching angle and curvature ratio of each bifurcation, but also strongly depended on the shape of the path generated by the cascade of branches. Secondary flow velocities were higher in the left bronchus than in the right bronchus. This spatial variation of secondary flow was well correlated with differing gas transport rates between the left and right main bronchus.<\/jats:p>","DOI":"10.1115\/1.2800855","type":"journal-article","created":{"date-parts":[[2008,2,21]],"date-time":"2008-02-21T20:37:32Z","timestamp":1203626252000},"page":"565-573","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":31,"title":["Spatial and Temporal Variation of Secondary Flow During Oscillatory Flow in Model Human Central Airways"],"prefix":"10.1115","volume":"121","author":[{"given":"G.","family":"Tanaka","sequence":"first","affiliation":[{"name":"Institute of Biomedical Engineering, Faculty of Science and Technology, Keio University, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Ogata","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Engineering, Faculty of Science and Technology, Keio University, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Oka","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Engineering, Faculty of Science and Technology, Keio University, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Tanishita","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Engineering, Faculty of Science and Technology, Keio University, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[1999,12,1]]},"reference":[{"key":"2019100604231949200_r1","unstructured":"Lunkenheimer P.
