Накратко на български

Нестабилностите при горенето в пръстеновидните камери на газовите турбини се анализират чрез изучаване на множество пламъци едновременно. Това помага за разработването на по-ефективни двигатели и електроцентрали, които да използват водород вместо въглеродни горива.

Annular Instabilities and Transient Phenomena in Gas Turbine Combustors

The gas turbine industry is a vital driver of innovation, economic growth, jobs, trade and mobility in the EU in both the aviation and power generation sectors. It is a multi-billion Euro high-technology industry whose future competitiveness depends on a new generation of creative engineers with multi-disciplinary skills who can accelerate the development of new innovations needed for flexible, efficient power generation and sustainable aviation. There is a significant and urgent need to move towards zero-carbon operation of gas turbines for power generation using hydrogen as fuel to reduce global CO2 emissions and increase energy security. Unlike renewables, gas turbines burning hydrogen can potentially deliver large-scale power in the short to medium terms and offer an attractive solution to the problem of energy storage. They can potentially also offer zero carbon aviation solutions. The development of next generation low-emission NOx zero-carbon gas turbines is hindered by unsteady combustion problems that are often only discovered late into development because we cannot yet predict them at the design stage. For reasons of cost and simplicity, we have been trying to solve these problems by studying them in isolation in single flames when, in reality, gas turbines have annular or can-annular combustor chambers with multiple flames. These systems are known to have different stability characteristics that need to be understood. ANNULIGhT has made significant progress in our scientific understanding of these problems by studying them in annular and can-annular combustor geometries. The main challenges addressed are: i) the occurrence of self-excited combustion instabilities in aeroengines and power generation gas turbines which take the form of azimuthal modes in large pressure fluctuations threatening structural integrity, ii) increased probability of lean Blow-off, which consequently makes iii) ignition and light-around more difficult. These latter two issues are safety critical for aeroengine certification yet very little is understood about the mechanisms which control these processes.

Цел на проекта

The gas turbine industry is a vital driver of innovation, economic growth, jobs, trade and mobility in the EU in both the aviation and power generation sectors. It is a multi-billion Euro high-technology industry whose future competitiveness depends on a new generation of creative engineers with multi-disciplinary skills who can accelerate the development of new innovations needed for flexible, efficient power generation and sustainable aviation.Low-emission gas turbines are confronted with unsteady combustion problems often only discovered late into development or in service because our scientific and understanding is insufficient to predict them at the design stage. For reasons of cost and simplicity, we have been trying to solve unsteady combustion problems by studying them in single (or multiple) sectors. The lack of success of this approach is a striking gap in our community and is hindering innovation. ANNULIGhT will break this paradigm by bringing together academic and industry leaders to provide a new generation of engineers with an innovative, structured, multi-disciplinary training programme combining cutting-edge theory, computational and experimental methods that exclusively focuses on annular combustion chambers as found in real gas turbines.ANNULIGhT presents a new and innovative research and training methodologies that exploits three revolutions that have recently taken place in the field of unsteady combustion; i) new computational methods based on Large Eddy Simulations applied to full annular chambers that can reproduce phenomena observed in real systems, ii) new annular combustion facilities enabling these phenomena to be studied in detail in the laboratory, and (iii) new high-speed imaging diagnostics which gives time-resolved information. ANNULIGhT aims to deliver a new generation of engineers to develop the innovations needed for low-emission technologies and increase the competitiveness of the European gas turbine industry.
