Study of the vortex breakdown in a conical swirler using LDV, LES and POD

Modeling and understanding the vortex breakdown is a key issue of modern Lean Premixed Combustors. The main difficulty of the problem is the unsteady behavior of this type of flow: Large structures resulting from vortex breakdown and the swirling shear-layers, affect directly the flame stabilization leading to heat-release fluctuations and combustion instabilities. Consequently, one needs to captu

Swirl stabilized premixed flame analysis using of LES and POD

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. Besides the beneficial effects, there are still some issues related to instabilities an

A Comparative Study of LES Turbulent Combustion Models Applied to a Low Swirl Lean Premixed Burner

Noise computation of a turbo-engine jet exhaust based on LES and lighthill's acoustic analogy

Increasing noise regulations at urban airports force jet engine manufactures to develop and build more quiet engines. Over recent years, a significant reduction in fan and mechanical noise has been achieved. However, the jet exhaust is the principal source of noise. The acoustical field that is generated by a turboengine jet exhaust running near the ground level is considered. The full equations o

Measurements and LES of a SGT-800 Burner in a Combustion Rig

The Siemens gas turbine SGT-800 is the largest industrial gas turbine produced by Siemens Industrial Turbomachinery (SIT) offering a dry low emission (DLE) capability below 15 ppm NOx. It has a very high reliability using an annular combustor system with passive damping and 30 DLE burners. To obtain a greater understanding of the mixing process and the flame dynamics and in order to further reduce

Mobilising for gender equality in (post)conflict Democratic Republic of Congo: The case of the Rien Sans Les Femmes Movement

Over the last few years, there has been a proliferation of different kinds of movements across the globe as citizens agitate for economic, socio-political and environmental change. In the Democratic Republic of Congo (DRC), where the country has been involved in a series of wars, attention has rather been eschewed towards the rape and sexual violence of women and girls. Using post-colonialism and
