Methane, ethane, and ethylene laminar counterflow diffusion flames at elevated pressures: Experimental and computational investigations up to 2.0MPa
Methane, ethane, and ethylene laminar counterflow diffusion flames at elevated pressures: Experimental and computational investigations up to 2.0MPa Report Title A newly designed high-pressure combustion facility was used to study the structures and extinction conditions of counter?ow diffusion ?ames in air for nitrogen-diluted methane, ethane, and ethylene, from 0.1 MPa to 2.0 MPa. Besides emp...
متن کاملInvestigation of the transition from lightly sooting towards heavily sooting co-flow ethylene diffusion flames
Laminar, sooting, ethylene-fuelled, co-flow diffusion flames at atmospheric pressure have been studied experimentally and theoretically as a function of fuel dilution by inert nitrogen. The flames have been investigated experimentally using a combination of laser diagnostics and thermocouple-gas sampling probe measurements. Numerical simulations have been based on a fully coupled solution of th...

15 صفحه اولPrediction of Sooting Tendency for Hydrocarbon Liquids in Diffusion Flames
A theoretical method for predicting the smoke point of pure hydrocarbon liquids is presented. The method is based on a structural group contributions approach and does not require any experimental procedures or information of fuel properties, other than the molecular structure of the fuel molecules. The proposed correlation is presented in the form of a multivariable regression. The average dev...
متن کاملThe Effect of Temperature on the Sooting Behavior of Laminar Diffusion Flames
The effect of temperature on soot formation in a laminar propane diffusion flame was investigated. The temperature of the flame on a Parker Wolf hard burner was varied by adjusting the inert nitrogen content in the oxidizer flow. Local soot aggregate properties, such as aggregate diameters and their number densities as well as soot volume fractions were determined using simultaneous laser light...
