Description

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. 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. The OH* chemiluminescence data References: [1] P. Weigand, R. Lückerath, and W.
