Characteristics of H2/air annular jet flames using multiple shear coaxial injectors
Journal of Fluid Science and Technology, 2014 The heat transfer characteristics for the process tubes of a cracking furnace and the combustion chamber wall of a liquid oxygen/gas hydrogen rocket engine, both of which use multiple nozzles, are very important in terms of performance and safety.

Non-linearities in the thermoacoustic response of a premixed swirl burner [PDF]
, 2009 PhDLean premixed combustion remains one of the simplest and most effective methods of reducing NOx emissions in industrial gas turbines. Lean premixed flames are however prone to an undesirable side effect known as combustion instability, reducing ...

Experimental investigation on flame characteristics in a porous-free flame burner [PDF]
Heat and Mass Transfer, 2020 Present work studies experimentally the flame characteristics of a premixed natural gas/air mixture in a porous-free flame (PFF) burner, and also it is compared with a conventional porous burner. For the PFF burner a hole is created at the center of the porous foam, which has a porosity of 87%, height of 22 mm and diameter of 90 mm, making a ...

Burned Gas Characteristics of Laminar Lifted Flame at the Beginning of Stream Heating
Journal of Thermal Science and Technology, 2011 This research experimentally investigates the exhaust gas characteristics of a methane-air lifted-jet flame with elevated stream temperatures up to 450 K. Emission indices of NOx and CO were measured by direct gas sampling using a gas detector tube.

An Autoadaptive Edge-Detection Algorithm for Flame and Fire Image Processing [PDF]
, 2012 The determination of flame or fire edges is the process of identifying a boundary between the area where there is thermochemical reaction and those without. It is a precursor to image-based flame monitoring, early fire detection, fire evaluation, and the

Burning velocity and the influence of flame stretch [PDF]
, 1991 A new technique is presented for determining burning velocities and stretch effects in laminar flames, and applied to a range of fuel/air mixtures. The speeds of expanding spherical flames, measured by high-speed schlieren cine-photography, are shown to
