1. Impacts of alternative combustion diluents and hydrogen addition on a swirl-stabilized flame related to gas turbine application
Sammanfattning : The global energy tendency leads to increasing attention on clean combustion technologies in order to eliminate adverse impacts on the environment. The utilization of oxyfuel combustion (CO2 acts as the only combustion dilution), flame diluents, and hydrogen fuel in gas turbine combustion provides a promising solution to reduce combustion pollutant emissions.

2. Swirl stabilized premixed flame analysis using of LES and POD
Sammanfattning : For environmental and human health reasons, the regulations on the emissions from combustion devices are getting more and more strict. In particular, it is important to abate the emission of pollutants deriving from combustion in gas turbines. A solution is the use of swirl stabilized, lean premixed combustion. LÄS MER
3. Interaction of sound waves with a swirl stabilized wood powder flame and their effects on flame characteristics
Sammanfattning : Swirling flows have been widely used for many years in engineering applications such as; chemical and mechanical mixing devices, separation units, spray drying technologies, turbo machinery and combustion systems. In practical combustion applications, swirl motion has been adopted to the incoming reactant flows in order to enhance the mixing of fuel and oxidizer and to improve flame stabilization and establishment, especially in regions of relatively low velocities, by recirculating hot product gas to the incoming reactants.

4. Experimental and Numerical Investigations of Flames Stabilized by Swirl Flow and Bluff-body:Flame Structures and Flame Instabilities
Sammanfattning : Combustion and its control are essential to our existence on this planet since we knew it. Nowadays, the largest share of the world’s electricity and most of our transportation systems are powered by combustion. In addition, industrial processes also rely heavily upon combustion. LÄS MER
5. A Numerical Study of Reacting Flows Using Finite Rate Chemistry
Sammanfattning : Fossil fuels will remain the main source of energy for mankind in theforeseeable future. Heat released in combustion of fossil fuels is alwaysaccompanied by emission of undesired pollutants. Environmental concernshave led to stringent emission rules for combustion industry speciallyfor reducing the amount of NOx production. LÄS MER
