标题： Simulation and analysis of turbulent flame and its effect on the wall of aero engine combustor

摘要： 本研究的主要目标是模拟航空发动机燃烧室中湍流火焰反应流的行为，并有助于分析火焰结构，以及在给定新鲜气体压力和温度的情况下确定燃烧的热力学参数的行为。数值方法基于使用Ansys-Fluent代码求解湍流燃烧的基本方程，其中选择K-e湍流模型，燃烧室的几何结构使用Ansys-workbench软件进行创建。随后，我们通过圆筒形燃烧室的壁面模拟瞬态温度场，并表征耐火材料的物理性能下的热膨胀、热弹性应力和应变。然后将获得的结果与科学文献中的结果进行比较。 显示英文摘要

摘要： The main objective of this study is to simulate the behavior of the reactive flow of the turbulent flame in aeronautical combustion chamber of the ALLISON-T56 turboprop, and contribute to the analysis of flame structure and determine for given pressure and temperature of fresh gas the behavior of the thermodynamic parameters of combustion. The numerical approach is based on the resolution of basic equations of turbulent combustion using Ansys-Fluent code where the turbulence model K-e is chosen, the geometry of the combustion chamber is made using Ansys-workbench software. Thereafter, we simulate the transient temperature field through the wall of a tubular combustion chamber, and the characterization of the thermal expansion, the thermoelastic stresses and strains with the physical properties of refractory materials. The obtained results are then compared with the results of the scientific literature
