In this study, experimental determination and modelling investigations for the explosion regions of 1,3-dioxolane/inert gas/N₂O and 1,3-dioxolane/inert gas/air mixtures were carried out and compared. The experimental measurements were carried out at 338 K and atmospheric pressure according to EN1839 method T using the inert gases N₂, CO₂, He and Ar. The results showed that the ratio of the lower explosion limit in N₂O (LEL_N2O) to the lower explosion limit in air (LEL_air) is 0.52 and the ratio of the maximum oxygen content in air (MOC_air) to the limiting oxidizer fraction.in nitrous oxide (LOF_N2O) is 0.36 + 0.02 independent of the inert gas. When comparing the inert gas amount at the apex based on the pure oxidizing component, which is O₂ in case of air, N₂O-containing mixtures need less inert gas to reach the limiting oxidizer quantity whereas the efficiency of inert gases is in the same order. The coefficients of nitrogen equivalency however were found to differ to some extent. The explosion regions of 1,3-dioxolane/inert gas/oxidizer mixtures were modelled using the calculated adiabatic flame temperature profile (CAFTP) method as well as corrected adiabatic flame temperatures. The results indicate good agreement with experimental data for CO₂, N₂ and Ar- containing mixtures. The noticeable deviations that occur when He is the inert gas are due to the lacking transport data of that mixture.

在这项研究中，对1,3-二氧戊环/惰性气体/ N ₂ O和1,3-二氧戊环/惰性气体/空气混合物的爆炸区域进行了实验确定和模型研究。根据EN1839方法T，使用惰性气体N ₂，CO ₂，He和Ar在338 K和大气压下进行实验测量。结果表明，N ₂ O的爆炸下限（LEL _N2O）与空气（LEL_空气）下限的比为0.52，空气（MOC_空气）中最大氧含量与极限氧化剂的比值。一氧化二氮（LOF _N2O）是0.36 + 0.02，与惰性气体无关。当比较基于纯氧化成分的顶点处的惰性气体量（在空气中为O _2）时，含N ₂ O的混合物需要较少的惰性气体才能达到极限氧化剂量，而惰性气体的效率则取决于相同的顺序。然而，发现氮当量系数有所不同。1,3-二氧戊环/惰性气体/氧化剂混合物的爆炸区域使用计算的绝热火焰温度分布图（CAFTP）方法和校正的绝热火焰温度进行建模。结果表明与CO ₂，N _2的实验数据吻合良好和含Ar的混合物。当氦气为惰性气体时，会出现明显的偏差，这是由于缺乏该混合物的传输数据所致。
