自動車火災実験の発熱速度と発生ガス濃度について

When a road tunnel fire, it is important to secure an evacuation environment for users by controlling the longitudinal wind velocity with ventilation equipment. Relatively old tunnels have a small internal cross-sectional area, which makes it difficult to control smoke and may require evacuation action in the smoke. In recent years, road tunnel fires have been studied to understand the diffusion of smoke and the evacuation environment, and experimental data on the amount of heat generated and smoke emission have been accumulated. However, data on the concentration of toxic gases contained in smoke are not enough understood.

In this report, we summarize and report on the relationship of CO and HCN concentrations with respect to the heat generation rate and smoke generation rate due to a light vehicle fire.
