Autor: Olaf Diers, Lena Voigt, Ingo Otterpohl, Eggert Magens, Johannes Heinze, Christoph Hassa

Publikováno v: Volume 3: Ceramics; Coal, Biomass, Hydrogen, and Alternative Fuels.

The production and emission of soot from Kerosene JET-A1 and a blend of a different JET-A1 and 30% HEFA was investigated in a realistic multisector combustor of Rolls-Royce Deutschland. Soot concentration measurements were performed at the exit as we

Experimental Investigation of a RQL Burner With Jet in Cross Flow Fuel Injection: Characterization of the Reacting Flow Field at Realistic Operating Conditions

Autor: Christoph Hassa, J. Gregory, T. Soworka, Thomas Behrendt, F. di Mare, Eggert Magens, Johannes Heinze, S. Ballantyne, Michael Schroll

Publikováno v: Volume 4B: Combustion, Fuels, and Emissions.

Future rich-burn/quick-quench/lean-burn (RQL) burners for aero engines face the challenge to further reduce the emission of soot. Alternative ways of fuel injection are therefore in the focus of modern RQL combustion systems. This contribution aims t

INVESTIGATION OF THE REACTING FLOW FIELD OF A LEAN BURN INJECTOR WITH VARYING DEGREE OF SWIRL AT ELEVATED PRESSURE CONDITION

Autor: Christoph Hassa, Johannes Heinze, Imon-Kalyan Bagchi, Eggert Magens, Michael Schroll, Ulrich Meier

Two RR Lean Direct Injection (LDI) injector versions with different amounts of pilot swirl were investigated. Experiments, performed at elevated pressure and temperature, corresponding to engine conditions at idle include Mie scattering. LII and abso

Characterization of Lean Burn Module Air Blast Pilot Injector With Laser Techniques

Autor: Christoph Hassa, Stefan Freitag, Ulrich Meier, Michael Whiteman, Christian Willert, Michael Schroll, Lena Lange, Waldemar Lazik, Johannes Heinze, Imon-Kalyan Bagchi, Eggert Magens

For lean burn combustor development in low emission aero-engines, the pilot stage of the fuel injector plays a key role with respect to stability, operability, NOx emissions, and smoke production. Therefore it is of considerable interest to character

Coherent Anti-Stokes Raman Scattering Temperature Measurements on an Air Breathing Ramjet Model

Autor: Adi Winandy, Sebastian Cordes, Hedwig Weisgerber, Eggert Magens, Michael Fischer

Coherent anti-Stokes Raman scattering was used to measure nitrogen single-pulse spectra at the entrance and exit area of a thrust nozzle. Thermodynamic nonequilibrium effects were proved at the exit of the hypersonic nozzle, belonging to an air-breat
