Liquefied petroleum gas (LPG) has potential pool fire risks due to its flammability. The configuration of pool fires plays a significant role when applying the solid flame model or point source model to assess the risks from heat radiation. However, no existing correlations can precisely predict the configuration of large LPG (100% propane) pool fires. To enhance the fundamental understanding on how pool diameter and wind velocity can influence the configuration of large LPG pool fires, an experimentally validated Computational Fluid Dynamics (CFD) model is employed to simulate fires using different burning rate models. Fire temperature profiles, flame heights, and flame tilts predicted by the CFD model were compared with empirical models and experimental data. Accordingly, new correlations for flame height and flame tilt as functions of pool diameter D and wind velocity u_w have been developed. The comparisons demonstrate that the new correlations have the best overall accuracy in the prediction of flame height and tilt for large LPG pool fires under different conditions (10 m ≤ D ≤ 20 m, 0 ≤ u_w ≤ 3 m·s⁻¹).

液化石油气（LPG）具有易燃性，因此有潜在的着火危险。当应用固体火焰模型或点源模型评估热辐射的风险时，池火的配置起着重要作用。但是，没有任何现有的相关性可以准确预测大型LPG（100％丙烷）池火的构造。为了增强对池直径和风速如何影响大型LPG池火灾配置的基本了解，采用了经过实验验证的计算流体动力学（CFD）模型来模拟使用不同燃烧速率模型的火灾。将CFD模型预测的火灾温度曲线，火焰高度和火焰倾斜与经验模型和实验数据进行了比较。因此，已经开发出D和风速u _w。的比较表明，该相关性具有的火焰高度和倾斜的预测最佳的整体精度在不同条件下大LPG池火灾（10米≤  d  ≤20μm时，0≤  ü_瓦特 ≤3米·秒^-1）。
