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
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
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.
Large-eddy simulations with a transported probability density function model coupled with a finite-rate chemistry is applied to study the ignition process of an n-heptane spray in a constant volume chamber with a premixed methanol-air atmosphere under conditions relevant to reactivity controlled compression ignition (RCCI) engines. Three reacting spray cases with initial methanol-air equivalence r
Be it in prose or be it in poetry, Charles Bukowski proposes anarchic protagonists, critical of the Establishment and absorbed in writing. Muses are plenty, but the real fuel for inspiration is alcohol, especially beer. Epic in poetry, abrupt in prose, Bukowski is unflinchingly honest and self-demythologizing. His hedonism and drunkenness are masks put on his revolt against the world and his own f
Strata compiles 37 conversations with artists whose work has made a significant contribution to the Italian and international art scene since 2000. This book is the personal account of a number of encounters, friendships, and professional relationships that Vincenzo de Bellis and Alessandro Rabottini have nurtured over the past twenty years. The conversations explore pivotal moments in each artist
