Boundary conditions of an experimental test bench to numerically investigate flame wall interactions using CFD

The data provides boundary conditions to numerically investigate the flame wall interactions of an experimental test bench at the Bundeswehr University of Munich. To fully describe the boundary conditions three data sets are available.
The first data set contains the mainflow boundary conditions of the test section upstream of the fuel injectors. The velocity and RMS-velocity fields are provided. The Large-Eddy-Simulations (LES) capability of ANSYS Fluent was used to create this dataset. The second data set describes the exit boundary conditions of the fuel injector into the test section at a momentum ratio of I = 10. Methane was used as fuel. LES by using the open source package OpenFOAM were applied for the data creation. The third data set describes the temperature distribution at the test section's wall. The data was derived from signals of wall-embedded thermocouples by using MATLAB and COMSOL and by running the inverse heat conduction method.

本数据集提供了边界条件，旨在对慕尼黑联邦国防军大学实验测试台的火焰壁面相互作用进行数值研究。为全面描述边界条件，共提供三个数据集。第一个数据集包含了燃料喷射器上游测试段的主流边界条件，其中提供了速度场和均方根速度场。该数据集通过使用 ANSYS Fluent 的湍流大涡模拟（LES）功能创建。第二个数据集描述了在动量比 I = 10 时，燃料喷射器进入测试段的出口边界条件，使用甲烷作为燃料。数据创建采用了开源软件包 OpenFOAM 进行 LES 计算。第三个数据集描述了测试段壁面的温度分布，数据是通过使用 MATLAB 和 COMSOL 以及逆向热传导法，根据嵌入在壁面中的热电偶信号推导而来。
