Sentence examples for maximum soot concentration from inspiring English sources

For the time-varying CH4/air flame, the simulations successfully predict that the maximum soot concentration increases by over four times compared to the steady flame with the same mean fuel and air velocities.

Maximum soot concentration depended on pressure according to a power law, where the exponent on pressure is about 2 for the range of pressures between 0.5 and 2.0 MPa, and about 1.2 for 2.0 to 4.0 MPa.

Although the peak PAH fluorescence signals and maximum soot concentrations do not occur at the same spatial locations, indirect evidence is presented that the species responsible for PAH fluorescence participate in either soot inception or growth.

Maximum line-of-sight soot concentration along the flame centerline scaled with pressure; the pressure exponent was about 1.4 for pressures between 0.2 and 0.73 MPa.

The second regime, occurring for oxygen indices higher than 25%, is dominated by soot formation; the rate of increase in the maximum soot volume fraction with the oxygen concentration is lower than in the first regime, whereas the fuel flow rate at the smoke point decreases.

Ethanol-doped methane flames displayed higher soot concentrations than those of neat methane flames at all pressures considered in the study; however, pressure dependence of maximum soot volume fraction is almost the same for both neat methane and ethanol-doped methane.

In contrast to prior suggestions that PAH fluorescence intensities scale with soot concentrations, the relative peak PAH fluorescence signals are observed to be 1.0 9.8 5.4 for the steady methane, propane, and ethylene flames, respectively, whereas the maximum soot levels follow a different trend of 1.0 19 39.

Continuous records of soot temperature and relative soot concentration within individual engine cycles are evaluated from images of soot radiation at two wavelengths (650 and 750 nm).

It is found that the soot concentration is nearly independent to CO2 concentration.

Soot concentration decreases with increasing the temperature while syngas concentration gradually increases.

Likewise, the peak soot concentration first increases with small amounts of air addition (or partial premixing of the fuel stream) and reaches a maximum value at ϕ∼24.
