Numerical simulation of flame and compression wave in far field for alternative fuel

提出了一种新的替代燃料泄漏与爆炸风险评估的数值模拟方法。在以往的工作中，爆炸损伤是用经验方法估计的。本研究的新方法是基于详细的物理现象和仿真模型。通过对替代燃料加热试验的实验和模拟，建立了泄漏模型。开发并简化了替代燃料的详细反应模型。在燃烧模拟中实现了反应模型，并用实验数据进行了验证。

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.
