327 両端にトンネルを持つ橋梁からの排気ガス拡散(S39-1 トンネルの空気力学と換気(道路と環境),S39 トンネルの空気力学と換気)  [in Japanese] 327 Exhaust Gas Diffusion from the Bridge with Tunnels at both Ends  [in Japanese]

In order to prevent exhaust gas diffusion from the bridge with tunnels at both ends, it is considered to installation of louver above the bridge. In this paper, the characteristic of louver has been grasped and the analysis technique that is imitating cars that were running continuously on the tunnel and the bridge using the technique of a sliding mesh was established. Therefore, it became possible to evaluate the influence on the environment in this case by numerical analysis.
