摘要: 航空发动机燃烧室几何结构复杂,湍流和化学反应存在强烈非线性相互作用,需要对流动和燃烧及其相互作用进行高精度高时空分辨率的刻画,目前燃烧室湍流燃烧数值模拟仍然是高难度的瓶颈问题之一。介绍了由北京航空航天大学航空发动机数值仿真研究中心、北京应用物理与计算数学研究所和中国工程物理研究院高性能数值模拟软件中心联合研发的AECSC-JASMIN软件主要框架、算法以及针对该软件的算例检验。在Sandia射流火焰、支板火焰和单头部燃烧室检验算例中,对比实验数据,射流和支板火焰预测结果与实验值一致;支板算例的平均相对误差在15%之内;单头部燃烧室模拟结果符合物理实际,总压损失与实验值基本吻合。说明AECSC-JASMIN软件可用于复杂结构高分辨率高精度湍流燃烧数值模拟。

Abstract: The complex geometry of the aero-engine combustion chambers and the strong nonlinear interaction between turbulence and chemical reactions require high precision characterization of the flow, combustion, and their interaction with high space-time resolution. Currently, the difficulty in numerical simulation of turbulent combustion in the combustion chamber remains one of the bottleneck problems. This article will introduce the main algorithm of the AECSC-JASMIN software, which is jointly developed by the Aeroengine Numerical Simulation Research Center of Beihang University, Institute of Applied Physics and Computational Mathematics, and CAEP Software Center for High-Performance Numerical Simulation, as well as the example verification of the software. It will be tested with Sandia`s jet flame, concave strut flame-holder, and single-head combustion chamber. Compared with the experimental data, the prediction results of the jet and concave strut flame-holder are consistent with the experimental values, with an average relative error within 15%. The simulation results of the single-head combustion chamber conform to the physical reality, and the total pressure loss is consistent with the experimental value. Therefore, AECSC-JASMIN software can be used for numerical simulation of high-resolution and high-precision turbulent combustion in complex structures.
