Tunnel effect

Summary

Reports on a research project showing how the geometry of a tunnel affects the heat release rate in tunnel fires. Describes the test methods and the results showed that the width of a tunnel has a significantly greater influence on the heat release rate of a fire than the height of the tunnel. Concludes therefore that in situations where the airflow is not restricted, a wider tunnel is a safer tunnel.
