Turbulent 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, 2015Abstract 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.

Flame synthesis of carbon metal-oxide nanocomposites in a counterflow burner
, 2020Core-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, 1995Abstract 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 ...
