Flame Speciation and Laminar Burning Velocity of Tetralin Flames Under Atmospheric Pressure

Energies
We present a combined experimental and modeling study of premixed atmospheric-pressure tetralin flames. Chemical speciation in near-stoichiometric (φ = 0.8–1.0) tetralin/O2/Ar flames was characterized by probe-sampling molecular-beam mass spectrometry ...
