Abstract

Scaling relations for tunnel fires have been extended to include the impact of pool sizes on Q of fires. The theoretical analysis deduced that in order to preserve a similar fire and smoke flow, the portion of pool fire sizes D_f/D_m should be proportional to the five-eighth power law of the characteristic length L*. A dimensionless parameter τ is introduced to eliminate the time diversity. It is defined as the fire-heating time for upper hot layer. Full-scale tunnel fire experiments were conducted with two fire sizes. A series of reduced scale experiments were carried out in the model tunnel (20:1). The experimental results enhanced the reliability of the theoretical models.
