Effects of fuel nozzle shape on soot emission of coflow diffusion flames

Nihon Kikai Gakkai ronbunshu, 2023
An experimental study was conducted on the effect of the shape of the fuel nozzle outlet on the suppression of soot emission from a coaxial flow diffusion flame. Three nozzle shapes were used, namely circular, square, and an equilateral triangle. Propane

Characteristics Of Large Diffusion Flames Burning In A Vitiated Atmosphere [PDF]

, 1991
Experiments concerning properties of large diffusion flames burning steadily in a vitiated atmosphere under conditions similar to those which may arise in a room fire are described. The effects of vitiation on the products of combustion and flame lengths,

Effect of Co-Axial Flow Velocity on Soot Formation in a Laminar Jet Diffusion Flame under Microgravity

Journal of Thermal Science and Technology, 2007
To examine the effect of low co-axial flow on soot formation in a laminar jet diffusion flame, microgravity experiments have been conducted. The tested co-axial flow velocity range is 0-7.3 cm/s, which is very difficult to provide on the ground because ...

Influences on the fraction of hydrophobic and hydrophilic black carbon in the atmosphere [PDF]

, 2011
Black carbon (BC) is a short term climate forcer that directly warms the atmosphere, slows convection, and hinders quantification of the effect of greenhouse gases on climate change.

Simulation of the Formation and Growth of Soot Aerosol Particles in a Premixed Combustion Process Using a Soot Aerosol Dynamics Model

Atmosphere, 2022
Recently, an aerosol dynamics model—the Soot Aggregate Moment Model (SAMM)—that can efficiently trace the size distribution and morphology of soot particles was developed.

Atmospheric ice nuclei in the Eyjafjallajökull volcanic ash plume [PDF]

, 2011
We have sampled atmospheric ice nuclei (IN) and aerosol in Germany and in Israel during spring 2010. IN were analyzed by the static vapor diffusion chamber FRIDGE, as well as by electron microscopy.

Soot formation and burnout in flames [PDF]

, 1980
The amount of soot formed when burning a benzene/hexane mixture in a turbulent combustor was examined. Soot concentration profiles in the same combustor for kerosene fuel are given.
