LIF-imaging of temperature and iron-atom concentration in iron nitrate doped low-pressure aerosol flat flames
To enable the investigation of the flame chemistry of precursor-laden nanoparticle forming spray flames in quasi-one-dimensional geometry, a matrix burner was developed in which a laminar flat flame is uniformly supplied with liquid aerosol. In the present work, the burner was used to study the inte...

| description | To enable the investigation of the flame chemistry of precursor-laden nanoparticle forming spray flames in quasi-one-dimensional geometry, a matrix burner was developed in which a laminar flat flame is uniformly supplied with liquid aerosol. In the present work, the burner was used to study the interaction of iron(III) nitrate as precursor dissolved in 1-butanol with the flame. Distributions of temperature and relative iron-atom concentrations were measured via OH and Fe laser-induced fluorescence imaging, respectively. Elastic laser light scattering was used to determine the spatial distribution of particles and droplets to characterize the burner and to obtain insight into the particle formation process. The matrix burner was operated with hydrogen or methane. The measured flame temperatures were compared with one- and three-dimensional CFD simulations supporting the development of reaction mechanisms for precursor-laden flames. |
