La capacit\u00e9 des syst\u00e8mes de ventilation des tunnels et les scenarios d\u2019op\u00e9ration ont \u00e9t\u00e9 d\u00e9finis dans le cadre des projets des m\u00e9tros de Gebze Dar\u0131ca (11 stations pour une longueur de 15.4 km) et de Fahrettin Altay-Narl\u0131dere Kaymakamlik (7 stations pour une longueur de 7 km). A cette fin, les normes nationales et internationales, les r\u00e8glementations et les sp\u00e9cifications techniques ont \u00e9t\u00e9 utilis\u00e9es.<\/strong><\/p>\n\n\n\n

Dans ces \u00e9tudes, des scenarios de feux de v\u00e9hicules dans les tunnels et des zones de r\u00e9gulations ont \u00e9t\u00e9 simul\u00e9s en utilisant Subway Environment Simulation (SES \u2013ventilation de tunnels). Ainsi, les capacit\u00e9s des ventilateurs ont \u00e9t\u00e9 calcul\u00e9es et les conditions aux limites ont \u00e9t\u00e9 d\u00e9termin\u00e9es par calcul CFD (Calculated Fluid Dynamics) pour les situations d\u2019urgence des stations.<\/p>\n\n\n\n

Suivant ces analyses SES, des mod\u00e9lisations en 3D des stations ont \u00e9t\u00e9 pr\u00e9par\u00e9es, puis transf\u00e9r\u00e9es aux modules CFD afin de v\u00e9rifier l\u2019efficacit\u00e9 des syst\u00e8mes de ventilation d\u2019urgence et des moyens d\u2019\u00e9vacuation. Les conditions aux limites r\u00e9elles d\u2019air ext\u00e9rieur et les ventilateurs op\u00e9rant conform\u00e9ment aux sc\u00e9narios d\u2019incendie en cas d\u2019urgence ont \u00e9t\u00e9 \u00e9valu\u00e9s conjointement, et les conditions aux limites du tunnel ont \u00e9t\u00e9 d\u00e9finies.   <\/p>\n\n\n\n

La d\u00e9termination du comportement des fluides est cruciale dans les calculs d\u2019ing\u00e9nierie. L\u2019analyse SES, qui est \u00e9galement d\u00e9finie comme une analyse 1 D, a \u00e9t\u00e9 faite en assumant que les param\u00e8tres comme l\u2019air, la vitesse et la temp\u00e9rature ne changent pas en direction horizontale (direction y) et en direction verticale (direction z) des tunnels, car la largeur et la hauteur du tunnel sont plus petites que la longueur du tunnel. D\u2019autre part, l\u2019analyse 3D fournit des avantages significatifs en termes de temps et de co\u00fbt en d\u00e9terminant des donn\u00e9es telles que le transfert de chaleur, la perte de pression et les d\u00e9bits en mod\u00e8les complexes. <\/p>\n\n\n\n
