针对以空气、煤油为反应物的涡轮试验台燃烧装置及其出口段建立了一种系统层次上的可以处理燃烧和流动耦合效应的模块化数值模型,并提出了一种基于混合物分数的热力计算方案和混合物分数方程,与基于质量流量混合比模型的仿真结果以及试验结果的对比表明,基于混合物分数的模型解决了以往研究中存在的瞬态仿真稳定性问题,并具有与试验结果一致的仿真精度。 A modular numerical model of combustion and flow coupling at the system level was established for the turbine test bed combustion unit with air and kerosene reactant and its exit section. A thermodynamic calculation based on the mixture fraction was proposed The comparison of the scheme and mixture fractional equations with the simulation results based on the mass flow mixing ratio model and the experimental results show that the model based on the mixture fraction solves the transient simulation stability problems in the previous studies and has the simulation consistent with the experimental results Accuracy.
