Sodium Spray Fire Simulations using CONTAIN-LMR

摘要

These results show that the Model Run #1 simulation of the T3 sodium spray fire using CLMR follows the same general trend seen for the experimental data. Due to inconsistent burning during the experimental sodium spray, errors between simulation and experiment vary from 0.0 to 0.08 during the spray (first 20 seconds). The CLMR results are highly sensitive to the f2 ratio and sodium droplet diameter. The experimental sodium droplet diameter remains unknown. Water-sodium droplet correlations have been investigated, but these correlations do not match with the CLMR results and have not been included here. With regards to heat transfer mechanisms, it is not well understood how the so-called "f2 ratio" used in pool fire physics affects or competes with other defined heat transfer models. Further investigation is needed to better understand how this ratio and the other heat transfer mechanisms compete with one another.
