Abstract：

When　a　fire　occurs　in　a　tunnel,　the　flame　will　be　tilted　to　a　certain　extent　due　to　the　effect　of　longitudinal　ventilation.　When　the　morphological　characteristics　change,　it　also　affects　the　combustion　and　heat　exchange　behavior.　In　this　study,　a　scaled　test　rig　with　a　ratio　of　1:6　was　established.　The　variation　of　the　inclination　angle　of　the　flame　with　the　wind　speed　and　the　source　power　was　obtained　under　different　longitudinal　wind　speeds.　Under　the　same　fire　source　power,　the　inclination　angle　of　the　flame　increases　as　the　wind　speed　increases.　The　degree　of　tilt　of　the　flame　is　not　only　related　to　the　longitudinal　wind　speed,　but　also　to　the　power　of　the　fire　source.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
