Premixed Turbulent Combustion In Counterflowing Streams
Combustion Science and Technology, 1989Abstract Premixed turbulent combustion of propane and air is studied experimentally using counterflowing axisymmetric jets. Attributes of this type of burner arrangement for studying turbulent combustion are discussed in terms of flame geometry, bulk and turbulent stretch rates, solid boundaries and measurement access.

Turbulent Premixed Combustion in a Boundary Layer
Combustion Science and Technology, 1984Abstract The turbulent boundary layer arising from the injection of cold reactants into a hot product stream is studied theoretically. By treating the rate of growth of the boundary layer as a small parameter and by assuming power law variations of global features of the layer the equations of a Reynolds stress closure are reduced to similarity form. A

The Thermal NO Reduction in Turbulent Premixed Combustion
2005The aim of this work is to investigate the influence of the flame temperature on the thermal NO formation varying the quantity of supplied combustion air and recirculated flue gases in turbulent premixed combustion. In the introduction is described the extended Zeldovich mechanism of thermal NO formation and the influence of the flame temperature as ...

Modeling partially premixed turbulent combustion
2001This paper investigates the process of partially premixed turbulent combustion in situations where the fuel is provided either as a liquid spray or a purely gaseous stream. In the former case, two-dimensional direct numerical simulations in association with a Lagrangian solver for the dispersed vaporizing phase are employed.

Marker fields for turbulent premixed combustion
Combustion and Flame, 2004Novel methods for generating a marker field in turbulent premixed combustion are described. The marker field is used to provide a mapping for the progress variable of the flame reaction. It is conjectured that at low Damkohler numbers conditional moment closure for the progress variable, conditional on the marking scalar, will be feasible.

Partially premixed diffusion flamelets in non-premixed turbulent combustion
Symposium (International) on Combustion, 1985The structure and extinction of partially premixed diffusion flamelets in a turbulent flow field is analyzed. It is shown that diffusion flamelets are disconnected if the variation of the mixture fraction around stoichiometric is large enough for the corresponding adiabatic flame temperature to be less than a characteristic freezing temperature. At the
