Abstract:

Developments m Gasoline Direct Injection, GDI, technology have enhanced the viability of long tenn SI engine development. Many automotive manufacturers are developing and offer production cars with first generation GDI engines. GDI fuel injection strategies provide power and effi ciency improvements, due to superior fuel metering, incylinder mixture preparation and the ability to run throttle-less under di fferent combustion modes depending on engine load. Although significant improvements in perfonnance and economy have been demonstrated, work is still required to optimise the GDI strategies

Abstract:

This thesis provides a detailed investigation of turbulent combustion modelling of liquid sprays. Modelling of liquid sprays is a challenging task due to the existence of a wide range of complexities in both liquid and gas phases and their interaction in the spray and combustion process. In such multiphase flow, there is a need to address all physical processes involved in each individual phase and jointly in the interaction of phases. In a multiphase flow, there are physical processes with respect to flow, energy, chemical reactions, and flame propagation. In the liquid phase, the physical pr

Abstract:

Spray models are increasingly becoming the principal tools in the design and development of gas turbine combustors. Spray modeling requires a knowledge of the liquid atomization process, and the sizes and velocities of subsequently formed droplets as initial conditions. In order to have a better understanding of the liquid atomization process,the breakup characteristics of plane liquid sheets in co-flowing gas streams are investigated by means of linear and nonlinear hydrodynamic instability analyses. The liquid sheet breakup process is studied for initial sinuous and varicose modes of di

Abstract:

This study was motivated by a need to better understand the sprays that can develop when oil leaks occur in gas turbine engines. Current gas turbine engines incorporate an extensive network of oil distribution pipes which deliver lubrication oil to bearings and seals at various locations across the engine. Parts of the oil pipe network are situated in hot, high pressure engine cavities where an oil leak, from a fractured pipe or leaking seal, could ignite and lead to an engine fire. Oil leaks in gas turbine engines create liquid injection in cross-airstream situations, a subject which has been

Abstract:

Nowadays the development of new Internal Combustion Engines is mainly driven by the need to reduce tailpipe emissions of pollutants, Green-House Gases and avoid the fossil fuels wasting. The design of dimension and shape of the combustion chamber together with the implementation of different injection strategies e.g., injection timing, spray targeting, higher injection pressure, play a key role in the accomplishment of the aforementioned targets. As far as the match between the fuel injection and evaporation and the combustion chamber shape is concerned, the assessment of the interaction betwe

The atomization and spray forming of liquid metals was studied. Melt break up algorithms were developed to predict the size distribution of the spray generated as well as secondary aspects of the atomization phenomena. In the model, which is based on the Surface Wave Formation (SWF) theory, the relative velocity between the gas and melt phase was thought to induce a sinusoidal disturbance on the surface of the melt column. Depending on the flow conditions such a disturbance could grow in amplitude and cause certain parts of the surface to be torn off the liquid column. A number of different ap

Abstract:

To adhere to the current requirements for NOx and CO emissions in combustion systems, modern land and air based gas turbine engines often operate in the fuel lean regime. While operating near the lean blow out (LBO) limit does reduce some harmful emissions, combustor stability is sacrificed and extinction becomes a major concern. To fully understand the characteristics of lean operation, an experimental study was conducted to map the time averaged flow field in a typical industrial, counter-swirling, liquid fuel combustor.

A liquid jet in a crossflow is often used to as a fuel injection method for combustion systems. Parameters such as penetration and core trajectory are used as characterization for the spray and specification of design criteria for combustor geometry. In addition to penetration and core trajectory, mapping the mass flux in space and time is an important part of modeling evaporation and global equivalence ratio throughout the combustor. Accurate prediction of these spray characteristics allows for a stable and robust combustor design. The break up of a liquid jet in a crossflow is an extremel

Abstract:

La fragmentation d'un jet liquide en un spray de gouttelettes est étudiée lorsque sa surface est soumise à un fort courant de gaz parallèle au jet. La visualisation du jet révèle qu'une étape transitoire précédant la formation des gouttelettes est la croissance de ligaments liquides à partir de la surface. En effet la surface est la croissance de ligaments liquides à partir de la surface. En effet la surface est instable vis-à-vis du cisaillement imposé par le courant gazeux. Initialement lisse elle est soumise à des ondulations axisymétriques grandissantes, dont la longueur d'onde est détermi
