TURBULENT JET DIFFUSION FLAMES
Progress in Energy and Combustion Science, 1976Publisher Summary This chapter discusses the turbulent jet diffusion flames of gaseous fuels. This system is simple compared to that in a diesel or gas turbine engine but nevertheless can throw much light on the mechanisms that are involved in the submodels used in describing the more complex systems.

Abstract Quenching of laminar flames entering a region of intense turbulence without mean flow was studied by instantaneous temperature, global and local chemiluminescence measurements, and fast Schlieren photography. The experiments were performed in a constant-pressure, square 50 × 50 mm tube for flammability limit studies for two integral scales ...

In the current study, the influence of turbulent mixing and local reaction rates on the transition to detonation of a turbulent shock-flame complex was investigated using a state-of-the-art large eddy simulation (LES) strategy.

Abstract Measurements of the turbulent structure of a premixed turbulent propane-air flame have been made by using a remote sensing, double-laser schlieren instrument which operates on a cross-correlation principle. Development, calibration, and improvements made for application to flames are presented and discussed.

Abstract A review is presented of turbulent transport phenomena in flames. Both large-scale turbulent transport and small-scale mixing processes are considered and various mechanisms of interaction between combustion and turbulent flow are identified. Flame-surface density descriptions of turbulent combustion at high Damköhler numbers

Turbulent nonpremixed flames are of interest in practical applications. They appear in jet engines, Diesel engines, steam boilers, furnaces, and hydrogen-oxygen rocket motors. Except for the turbulent premixed combustion in many spark-ignited engines (Otto cycles), most combustion is turbulent nonpremixed.

A work on turbulent premixed combustion is timely because of increased concern about the environmental impact of combustion and the search for new combustion concepts and technologies. An improved understanding of lean fuel turbulent premixed flames must play a central role in the fundamental science of these new concepts. Lean premixed flames have the

According to the Fourier integral theorem, a turbulent velocity field can be represented as asuperposition of plane sinusoidal shear waves of all orientations and wavelengths. The present paper is concerned with the analysis of the passage of a single representative shear wave through a plane flame front.
