comprising four distinct features providing improved performance: A sculpted chamber comprising D-shaped configuration; a fuel flow interference needle multiply comprised with bevel zones; easily accessible needle advancement and retraction means; and a centrally disposed auxiliary fuel jet aperture emission ...
The EEM spectrometer has been fiber-coupled to permitin situmeasurements of jet turbine oil contamination of jet fuel. Parallel Factor (PARAFAC) analysis as well as Principal Component Analysis and Regression (PCA/PCR) were used to quantify oil contamination in a range from the limit of detection...
It is likely that fuel refinements will advance in the future and be an important factor in emission reductions. A newer synthetic jet fuel (Fischer-Tropsch Synthetic Paraffinic Kerosene) under development to replace JP-8 in the future, was evaluated for toxicity in the required range of tests ...

In conclusion, there is no positive effect in using the Jet A1 in the diesel engine except for the reduction of NOemission and the decrease of the freezing point. 展开 关键词: Jet Al Aviation fuel Diesel engine Emission Engine performance ...
Local flame extinction occurred frequently when subjected to an excessive strain rate, indicating that intense mass transfer of fuel and air occurs radially inward at the flame surface. 展开 关键词: NO_x emission resonance frequency flame-vortex interaction entrainment velocity flame surface area local...
The present definition of the energy separation factor renders its distribution independent of the jet Reynolds number; except for axial locations between about 0.3D and 4D. The development of energy separation in the region close to the nozzle exit is faster when the jet Reynolds number is ...
(2) The NOx emission index for turbulent partially premixed flames with a fixed fuel flow rate and a fixed overall equivalence ratio is independent of ΦB for lower levels of partial premixing (5 ≤ΦB≤∞). (3) At intermediate levels of partial premixing (1.5 ≤ΦB≤ 5), the NOx em...
“We feel very strongly about a path to zero emissions in big jets, and the blended wing airframe can deliver 50% lower fuel burn and emissions,” Tom O’Leary, co-founder and CEO of JetZero, told CNN in August 2023. “That is a staggering leap forward in comparison to what the indu...
Section 5 covers emission line lobes and the alignment effect, which have been connected to outflows and jet-induced star formation outside the host galaxies. Another feature of high-redshift radio galaxies are associated absorption line systems, which have been interpreted as halo shock waves ...
