A one\u2010fifth scale experimental model of a real tunnel is the target model to be simulated. To achieve this, studies on the effects of different boundary conditions, in particular, the wind speed, are carried out on smaller tunnel structures with the same hydrogen inlet boundary conditions. The results suggest a threshold\/limiting value of air speed through tunnel. The target model computed with the most suitable boundary conditions shows some agreement with the experimental ones. A method to compute the buoyancy factor used in the code is also presented.<\/jats:p>","DOI":"10.1155\/2012\/846517","type":"journal-article","created":{"date-parts":[[2012,5,13]],"date-time":"2012-05-13T21:03:25Z","timestamp":1336943005000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Modelling Considerations in the Simulation of Hydrogen Dispersion within Tunnel Structures"],"prefix":"10.1155","volume":"2012","author":[{"given":"Idris","family":"Ismail","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisayoshi","family":"Tsukikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Kanayama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,5,13]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"crossref","unstructured":"SwainM.
