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

A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. Samtidigt möjliggör ökad beräkningskraft i moderna datorkluster att detaljerade simuleringar kan utföras för att stuClimate change is affecting our world and a more sustainable society is needed. The aviation industry is in need of change but aero-engines are very complex and take time to develop. Thermoacoustic instabilities have the power to destroy an engine, but also to reduce the environmental impact. At the same time, increasing computational power allows detailed simulations to be executed in order to st

LES study of diesel flame/wall interaction and mixing mechanisms at different wall distances

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

LES investigation of heat transfer in a tube with irregular roughness at moderate Prandtl numbers

Wall-bounded turbulent flows are central to a wide range of engineering applications, where surface roughness can significantly influence both frictional drag and convective heat transfer. While the momentum effects of roughness have been significantly advanced in the literature, the thermal counter parts remain insufficiently understood. This study addresses the critical gap in understanding roug

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
