Abstract
For large space, large-scale construction of new modern design can not meet the specification requirements, in a typical full-size big warehouse space, carry out a comparison of launching full-scale fire experiments and numerical simulation, and have errors analysis combined with related data. The flue gas temperature of certain height from fire source and fire heat release rate is obtained by experiment and simulation, and made the relevant error analysis. The study results show that: the temperature of test is lower than in numerical simulation; and the HRR is the favorable between test and simulation. Conclusions are as follows: the full-scale fire experiments can be more truly reflect the dynamics of fire combustion process, but in the full-scale fire experiments, the large thermocouple system, due to the large distance of temperature signals transmitting to the data collection system and other reasons leading to the certain degree of error; numerical simulation is idealized calculation process, its setting of associated performance parameters will result in an unreasonable degree of error, overall, the experimental results and simulation results are favorable.
