Local burning velocity in a Bunsen jet flame [PDF]
Comptes Rendus. Mécanique, 2012 A PIV-based system has been set-up for the simultaneous measurement of the local burning velocity of premixed flames and the flame stretch due to the flame front curvature and the incoming flow strain rate. For moderately short jet flames, these measurements allow an indirect determination of the Markstein length, according to Clavin and Joulin (C–J ...

Experimental investigation of the laminar burning velocity of iron-air flames in a tube burner
Applications in Energy and Combustion Science, 2023 This paper presents the results of experimental measurements of the laminar burning velocity of iron-air-flames in a model tube burner. Carbonyl iron powder with an average Sauter diameter of about 13 µm was mixed with air at ambient temperature and ...

Modeling radiative and climatic effects of brown carbon aerosols with the ARPEGE-Climat global climate model [PDF]
Atmospheric Chemistry and Physics, 2022 Organic aerosols are predominantly emitted from biomass burning and biofuel use. The fraction of these aerosols that strongly absorbs ultraviolet and short visible light is referred to as brown carbon (BrC).

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2008 This study is made to attempt to establish a prediction model of tubulent burning velocity for hydrogen mixtures based on the local burning velocity of turbulent flames instead of laminar burning velocity. The turbulent burning velocity characteristics of the specific mixtures having the same laminar burning velocity SL0 with different equivalence ...

Experimental Study on Local Flame Properties of Hydrogen Added Hydrocarbon Premixed Turbulent Flames
Journal of Thermal Science and Technology, 2009 This experimental study is performed to investigate directly the local flame properties of turbulent propagating flames at the same weak turbulence condition (u'/SL0=1.4), in order to clarify basically the influence of the addition of hydrogen to ...

Fluid-mechanical structure of methane-air and propane-air turbulent premixed flames
Nihon Kikai Gakkai ronbunshu, 2015 The flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic of turbulence have been closely examined by using a three-color six-beam LDV system.
