A new numerical simulation approach is proposed for a risk assessment of the leak and the explosion of alternative fuel. The explosion damage has been estimated by empirical procedure in previous works. The new approach is based on the detailed physical phenomena and simulation model in this study. The experiment and simulation of the heating test for alternative fuel construct the leak model. The detailed reaction models for the alternative fuel has been developed and reduced. The reaction models are implemented in the combustion simulation and validated with experimental data.

提出了一种新的数值模拟方法来评估替代燃料的泄漏和爆炸风险。在以前的工作中，爆炸损害是通过经验程序进行估计的。新方法基于本研究中详细的物理现象和模拟模型。通过替代燃料加热试验的实验和模拟，构建了泄漏模型。替代燃料的详细反应模型已经开发并简化。反应模型在燃烧模拟中实现，并通过实验数据进行验证。
