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 ...

Some Remarks on the Boundary of Thermodynamic Stability

Entropy, 2023
In this paper, we have considered some elements of the classical phenomenological theory of thermodynamic stability, which seem controversial and ambiguous. The main focus is on the conditions of the stability boundary; a new version of the derivation of
