Manuel Vogel, together with Jan Kaufmann, will investigate the dynamics of spray flames of different premixing degrees within the framework of a project financed by the BMWi and General Electric Power (LaBreVer).
Fabian Marquez Macias investigates the flow in novel combustion chambers with jet flames. The aim of the project is to perfect the uniform distribution and mixture of fuel and air and to develop suitable design methods. Financing is provided by the BMWi and Siemens Power Generation (LaBreVer).
Jonathan McClure continues Frederik Berger's work on high-frequency combustion instabilities in axially stagged combustion chambers with flame stabilization via self-ignition. This project is financed by the DFG, but is also of particular technical interest, as Ansaldo Energia develops gas turbines with such innovative combustion chambers that are particularly suitable for the use of alternative fuels and exhibit particularly good partial load behaviour.
A project financed by Solar Turbines in San Diego, CA, USA to improve the operational reliability of premix burners for smaller gas turbines using alternative fuels is currently being launched. These are more reactive than natural gas and often contain high amounts of hydrogen. Methodologically, the work will be based on the approaches developed by Matthias Utschick. The focus is on improving the basic understanding of the causes of flame flashbacks. The project will be carried out by Saskia Flebbe and Simon Tartsch, who will both start their work in July/August.
Our team dealing with flame acceleration and detonation will be strengthened by Dario Zivkovic, who will pursue the goal to develop a numerical calculation method based on many years of numerical preliminary work, which can be used in the whole range of incompressible flows with slow deflagration, over fast flames up to DDT and detonative flame propagation.
