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

In this paper, the flame-wall interaction of reacting diesel spray under engine like conditions is investigated using large eddy simulations. The aim of this study is to understand the influence of the distance between the wall and the spray nozzle on the air entrainment rate, which is a key variable in formation/oxidation process of soot. Three experimental cases are investigated, a free jet case

Large eddy simulations are performed for a single- and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow ratios but with droplets of different sizes. Multiphase JICF have stronger counter-rotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover, their trajectories are higher and their induced wake

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

Nu påbörjas årets lönerevision vid Luleå tekniska universitet som avser perioden 2024–10–01 –– 2025–09–30. Även i år har vi ett sifferlöst avtal. För medlemmar i Saco tillämpas på LTU lönesättande samtal vilket innebär att du som anställd i samband med lönerevisionen ska ha två samtal med din närmaste chef. Det första samtalet är tänkt att vara ett ömsesidigt utbyte av information avseende din pre

The savanna ecosystem is one of the most dominant and complex terrestrial biomes, deriving from a distinct vegetative surface comprised of co-dominant tree and grass populations. While these two vegetation types co-exist functionally, demographically they are not static but are dynamically changing in response to environmental forces such as annual fire events and rainfall variability. Modelling s

Popular Abstract in Swedish Energibalansen vid jordytan är av avgörande betydelse för Jordens alla ekosystem men när det gäller Arktiska och sub-Arktiska ekosystem är kunskapen bristfällig. I dynamiska system som klimatsystemet, påverkas utbytet av energi, vatten och växthusgaser av små förändringar i ekosystemen. Syftet med denna avhandling är därför att skapa ökad kunskap och en tydligare bild aThe surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. Therefore, this thesis aims to draw a conclusive picture of the surf

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
