Predicting the Heat Release Rate of the Storage Tank Pool Fires Using the Liquid Vaporization Model

Abstract

This study is a preliminary research to specify fire scenarios in storage tanks and evaluate the fire size based on the type of fuel and diameter of the storage tank by applying the liquid evaporation model of FDS . FDS version 6.7.6 was used in the analysis, and the computational domains were established based on the pool diameter with the same proportion. The results obtained from the FDS model indicated that the heat feedback to the fuel surface was relatively well matched with the previous empirical correlations and experimental results. The FDS model showed a relative error within 15% compared with that of previous empirical correlation and showed excellent linearity with respect to the size of the analyzed fuel. The present study contributes to expanding the applicability of FDS models in the fire safety analysis of large storage facilities. Additionally, a comparison analysis with experimental results is required to assess the reliability of heat release rate estimation.
