Characteristics of MILD combustion of CH₄-CO₂ jets in a piloted burner – Laser-diagnostic and LES studies

Fundamental characteristics of the reaction-zone structure for CH4-CO2 jets, mimicking a fuel of high CO2 contents such as biogas, burning in a heated coflow on a piloted jet burner have been investigated. Jet flames under diffusion and MILD combustion conditions were studied using planar laser-induced fluorescence (PLIF) of O-atom radicals and CO for different CO2 contents of the fuel jet. Numeri

LES of hydrogen enriched methane/air combustion in the SGT-800 burner at real engine conditions

DLE (Dry Low Emission) techniques are widely used today to reduce the harmful NOx emissions associated with high combustion temperatures. In many DLE systems the fuel and air are premixed which effectively keep the flame temperature as low as possible, ideally equal to the turbine inlet temperature. By using premixing stability issues such as flash back and combustion driven dynamics may occur. Op

LES of the interaction between a premixed flame and complex turbulent swirling flow

In this paper the Triple Annular Research Swirler, a fuel injector characterized by complex design with three concentric air passages, has been studied numerically. A swirl-stabilized lean premixed flame has been simulated by means of Large Eddy Simulation. The computations characterize successfully the dynamics of the flame and their interactions with the complex swirling flow. The flame is stabi

À la recherche d'un public parlant: les médias et la democratie.

The traditional notuion of democracy being anchored in discussions among citizens is highlighted. The chapter makes the claim that while civic talk is central to the life of democracy, there are many socio-cultural factors that impede poitical discussion. Also, while formal deliberation is important, even the free-flowing, messy and unpredictable converations of everyday life can give rise to the

Le réconfiguration de la culture civique

This chapter introduces the notion of civic culture as a frame for understanding political engagement and civic agency. In particular, the role of the media is underscored in shaping civic cultures; these include such dimensions as knowledge, values, practices and identities.
