Lewis Number Effects on Turbulent Premixed Flame Structure [PDF]

open access: yesCombustion Science and Technology, 1993
ABSTRACT The influence of the Lewis number on turbulent flame front geometry is investigated in a premixed turbulent stagnation point flame. A laser tomography technique is used to obtain the flame shape, a fractal analysis of the multiscale flame edges is performed and the distribution of local flame front curvature is determined. Lean H2/Air and C3H8/

Catalytic Acetylation of Aromatics with Metal Chlorides and Solid Acids − a Comparative Study

open access: yesEurasian Chemico-Technological Journal, 2004
Evaluation of catalytic performances of selected metal chlorides such as AlCl3, SnCl4, ZnCl2, FeCl3, InCl3 and GaCl3 with solid acids such as sulfated zirconia, and zeolite beta was accomplished for acetylation of anisole, toluene and naphthalene ...

Effect of the Reynolds and Lewis number to the fuel droplet vaporization

open access: yesThermal Science, 2023
In this work we present the effect of Reynolds and Lewis numbers on the fuel droplet vaporization of n-heptane. This study allows us to fully understand the vaporization phenomenon of fine fuel droplets (spray) in energy systems in order to improve combustion efficiency, reduce the formation of pollutants and unburned materials such as CO and NOx.

Fuel Lewis number effects in unsteady Burke-Schumann hydrogen flames

open access: yes, 2005
Flame response (as determined by temperature and flame thickness) to unsteady hydrodynamics has been measured in acoustically pulsed Burke-Schumann hydrogen flames at two different oscillation frequencies and amplitudes.

Antitumor effect of lysine-isopeptides

open access: yesCancer Cell International, 2002
Isopeptides (ε-peptides) of lysine, with a given Mw and low polydispersity (10–400 units), were synthesized to study the relationship between their chemical structure and biological effect.

Lewis number effects on lean premixed combustion characteristics of multi-component fuel blends [PDF]

open access: yes, 2022
Variation in natural gas composition, alongside the potential for H2 enrichment, creates the potential for significant changes to premixed flame behaviour.

Combustion mechanism of propane-air swirling premixed flame near lean flammability limit

open access: yesJournal of Thermal Science and Technology
This study investigated a premixed propane-air flame in a partially tapered swirl burner. Experimentally, we found that a flame resembling a morning glory flower formed at an equivalence ratio near the lean flammability limit.

Effects of radiation, curvature, and preferential diffusion on the extinction of laminar non-premixed flames

open access: yesAIP Advances, 2022
The combined effects of radiative heat loss, curvature, and preferential diffusion on laminar non-premixed flames (or flamelets) are investigated in this work by using asymptotic analysis.
