摘要
采用自定义标量法模拟丙烷扩散燃烧,该方法通过把反应组分定义为Fluent程序的自定义标量、化学反应速率作为源项求解质量、动量、能量和组分守恒方程,并用化学反应引起的能量变化修正能量方程。考虑了详细的化学反应机理,整个燃烧反应机理包括27种化学物质(不含N_2)和83个基元反应。合理地模拟出了丙烷的燃烧过程,并将火焰的长度、温度、丙烷、氧气以及中间产物的分布与实验数据进行比较。
Self-define scalar method is used to simulate propane diffusion combustion process.This method defines reaction compositions as self-define scalars in Fluent,computes the mass,momentum, energy and composition conservation equations through defining chemical reaction as source term,and modifies the energy equation by the energy change caused by chemical reaction.A detailed chemical kinetic reaction mechanism is considered,which consists of 27 chemical species and 83 elementary chemical reactions.Comparisons have been made on flame length,temperature,and C_2H_2 distribution between simulated and experimental data.
