Abstract

A general model describing the combustion of mixed gases is proposed, which accounts for the chemical work and assumes a single chemical reaction. An energy equation is written for an arbitrary mixture of fuel/oxidizer/combustion product. The combustion of an H₂/O₂ mixture is considered on the basis of the model. Modeling is carried out for two options: with and without account for the dependence of the heat capacity of the mixture components H₂, O₂, and H₂O on temperature. The chemical work has a positive sign, and its relative contribution to the main characteristics of the process (temperature and burning rate) is estimated at 3.9 and 19%.

化学作用对H2 / O2混合物火焰温度和燃烧速率的影响

摘要

提出了一个描述混合气体燃烧的通用模型，该模型考虑了化学功并假设了一个化学反应。针对燃料/氧化剂/燃烧产物的任意混合物编写了一个能量方程。在该模型的基础上考虑了H ₂ / O ₂混合物的燃烧。建模有两种选择：考虑和不考虑混合物组分H ₂，O ₂和H ₂ O的热容量对温度的依赖性。化学工作具有积极的迹象，其对过程主要特征（温度和燃烧速率）的相对贡献估计为3.9％和19％。
