“…The pool fires should be burned longer enough to get the smoke temperature to reach a steady state at far away from the fire, for example, +800 m or farther. And infrared beams will also be tried to track the smoke layer position vertically, which had been used by us in the former tests in a full scale underground corridor [14]. All of these works including model verification and further better equipped tests above will be done in the future.…”

Three full scale tests were conducted in a road tunnel to study the smoke spread with different fire sizes and wind speed conditions. The smoke temperature under the ceiling, the smoke layer height distribution and the travel of the smoke front in a 1000 m long domain along the road tunnel were measured. Results showed that wind speed had much influence on the spread of smoke in the tunnel. When wind speed was such low as less than 1 m/s, a smoke layer could form and stabilize all along the tunnel. But when the wind speed was such high as more than 2 m/s, smoke layer could only be maintained in a distance of about 400 m in the downstream. The slowdown of the traveling of the smoke front in the downstream along the tunnel was more obvious when the wind speed was smaller. All these full scale data presented here can be used for further study on the verification or improvement of existing fire models for enhancing their applicability to such long tunnels.

“…In this section, computational settings and parameters for the validation case study as investigated experimentally by Hu et al (2005) are outlined, and the results for this case are presented. These settings are used in a second validation study and eventually in the analysis of the fire safety of semi-open car parks.…”

“…Full-scale experimentation is considered to be the most reliable among the three methods. Hu et al (2005) conducted full-scale experiments in an 88 m long corridor to study the variation in smoke temperature and velocity under the ceiling. The smoke temperature and velocity showed an exponential decay along the corridor.…”

A reduced-scale (1:4) building corridor model was prepared to investigate the heat release rate (HRR) and smoke diffusion in a building corridor. Trays with heptane as fuel were used as fire sources. Three different sizes of trays were involved in this study to investigate the different HRRs. The results revealed that fire associated with larger trays exhibited a steeper power-law growth and decay. The temperature distributions in the corridor for the three cases showed similar tendencies. The temperature in the upper part of the corridor was relatively high, which decayed sharply along the corridor. However, the temperature in the lower part of the corridor was approximately the ambient temperature. Numerical simulation was also introduced to obtain more details regarding the temperature. The ceiling temperature was studied by using dimensionless parameters. The correlation between the ceiling temperature and the distance was fitted by using an exponential equation, and significant fitting results were obtained. Moreover, the vertical average temperatures in the corridor were also studied. The result indicated that greater HRRs led to higher vertical average temperatures with steeper growths and decreases.
