Turbulent effects on the flame behavior of turbulent counterflow nonpremixed flames

open access: yesTurbulent effects on the flame behavior of turbulent counterflow nonpremixed flames
The flow field of the turbulent counterflowing stream with and without nonpremixed flames, and the behavior of diffusion region of turbulent nonpremixed flames have been investigated experimentally. The turbulent characteristics of each side flow in a counterflowing stream would be regarded as keeping their initial turbulent characteristics from one ...

Accuracies of laminar counterflow flame experiments

Combustion and Flame, 2015
Abstract Counterflow configurations are useful for investigating the structures of premixed, non-premixed, and partially premixed flames. Ignition and extinction conditions also are readily measured in this configuration. There is a wide range of different possible designs of apparatus to be used in such measurements.

The unsteady investigation of methane-air premixed counterflow flame into newly proposed plus-shaped channel over palladium catalyst

Energy, 2019
In this paper, the time dependent study of methane-air premixed counterflow flame into a newly proposed plus-shaped channel, in order to obtain effects of palladium catalyst surfaces on the flame structure and pollutant emissions, is described.

Counterflow heptane flame structure

Proceedings of the Combustion Institute, 2000
Results are reported for thermocouple and gas-chromatographic measurements of profiles of temperature and of concentrations of C 7 H 16 , C 5 H 10 , C 4 H 8 , C 4 H 6 , C 3 H 6 , C 2 H 6 , C 2 H 4 , C 2 H 2 , CH 4 , CO, and CO 2 in two laminar counterflow n -heptane flames having measured flame temperature of 2100 K, at an oxidizerside potential-flow

Flame synthesis of carbon metal-oxide nanocomposites in a counterflow burner

, 2020
Core-shell carbon metal-oxide nanocomposites are synthesized in a well-defined counterflow burner. Benefitting from the two-nozzle configuration, the nanocomposite morphology can be controlled by adjusting the precursor loading rate and fuel mass ...

Counterflow diffusion flames with unsteady strain rates

33rd Aerospace Sciences Meeting and Exhibit, 1995
Abstract The counterflow diffusion flame subject to time-varying strain rates is studied analytically in order to assess the effect that unsteadiness caused by turbulent flows might have on laminar flamelets. The characteristic unsteady time considered is of the same order as the characteristic flame time, which is represented by the reciprocal of the ...
