Determination of combustion gas temperatures by infrared radiometry in sooting and nonsooting flames [PDF]

Flame temperatures in nonsooting and sooting environments were successfully measured by radiometry for pre-mixed propane-oxygen laminar flames stabilized on a water-cooled, porous sintered-bronze burner. The measured temperatures in the nonsooting flames

Chemical effects of natural gas components on polycyclic aromatic hydrocarbons and soot formation in inverse diffusion flames

Case Studies in Thermal Engineering
This work investigates the chemical effects of ethane, propane, and butane substitution for methane on flame properties and sooting behaviors in inverse diffusion flames of natural gas in different ratios by a decoupling method.

Upper-atmosphere Aerosols: Properties and Natural Cycles [PDF]

, 1992
The middle atmosphere is rich in its variety of particulate matter, which ranges from meteorite debris, to sulfate aerosols, to polar stratospheric ice clouds. Volcanic eruptions strongly perturb the stratospheric sulfate (Junge) layer.

Experimental and numerical investigations of soot formation in propane laminar coflow flames in O2/N2 and O2/CO2 atmospheres

Case Studies in Thermal Engineering
Oxygen-rich combustion is a new type of clean combustion technology with important application prospects. At present, there are few detailed analyses on the mechanism changes of soot formation under oxygen enrichment of propane.

Shock-tube measurements of carbon to oxygen atom ratios for incipient soot formation with C2H2, C2H4 and C2H6 fuels [PDF]

The critical atomic carbon to oxygen ratios, Phi sub C, for incipient soot formation in shock heated acetylene, ethylene, ethane/oxygen/ argon mixtures was measured over the temperature range 2000 K to 2500 K for reactant partial pressures between 0.1 ...

Dispersion of sound in a combustion duct by fuel droplets and soot particles [PDF]

Dispersion and attenuation of acoustic plane wave disturbances propagating in a ducted combustion system are studied. The dispersion and attenuation are caused by fuel droplet and soot emissions from a jet engine combustor. The attenuation and dispersion
