In order to analyze the radiation thermal transfer of the LPG tank under the pool fire effectively, the wavelet
finite element method has been applied in this research. First, the theoretical researches on the pool fire and the wavelet
finite element method are summarized respectively, and some patents related to the wavelet finite element method have
applied it in some engineering. Second, the basic theory of the wavelet finite element method is established. Next the thermal
radiation transfer model is analyzed, and the flame model is discussed. Then the thermal radiation analysis of the LPG
tank under the pool fire is carried out based on wavelet finite element method and experimental test. Finally, the affecting
factors of the thermal radiation for the LPG tank under pool fire such as filling rate and wind strength are analyzed, and
the corresponding thermal radiation rules are obtained.
