Thermal, optical and chemcial dataset of flat premixed Laminar CH4/air standard flames
收藏资源简介：
This dataset contains measurements of the thermal and chemical properties of eleven laminar premixed methane-air standard flames previously defined by the DLR Institute of Combustion [1] using a flat flame burner. All properties refer to a height of 15 mm above the sintered porous metal plate. We complement the existing dataset with infrared thermal imaging, photographs, heat flux density measurements and OH*-chemiluminescence for each of the conditions. In addition, the thermochemical properties for the region of interest are calculated using the open-source chemical kinetics software cantera [2]. The code is made available here: https://doi.org/10.5281/zenodo.4306644 Data in Brief article is available here: https://doi.org/10.1016/j.dib.2022.108281 The thermal imaging data is acquired with a multispectral camera equipped with eight filters for different spectral bands. The filter specifications, as well as the laboratory conditions (temperature, humidity and barometric pressure), are given for each test. The heat flux density is measured with a water-cooled gage. The gage sensitivity, cooling water temperature and raw data are given below. References: [1] P. Weigand, R. Lückerath, and W.

本数据集包含由德国航空航天中心（DLR）燃烧研究所[1]此前利用平面火焰燃烧器（flat flame burner）定义的11组层流预混甲烷-空气标准火焰的热学与化学特性测量数据。所有特性参数均取自烧结多孔金属板上方15 mm高度处的位置。我们为现有数据集补充了各工况下的红外热成像图像、实物照片、热流密度测量数据以及OH*化学发光数据。此外，本研究采用开源化学动力学软件Cantera（cantera）计算了目标区域内的热化学特性。 本数据集配套代码已公开于：https://doi.org/10.5281/zenodo.4306644 配套的《数据简报》（Data in Brief）研究论文可参见：https://doi.org/10.1016/j.dib.2022.108281 红外热成像数据由搭载8个不同光谱波段滤光片的多光谱相机采集获取，各测试的滤光片规格以及实验室环境参数（温度、相对湿度与大气压强）均已给出。热流密度采用水冷式热流计进行测量，该热流计的灵敏度、冷却水温度以及原始数据均已在下文列出。 参考文献： [1] P.
