Single Sector Combustor

. Air flow guidance of an aero engine combustion chamber . Optional extended optical access combustor

High pressure combustion test rig (up to 20 bar) offering three-way optical access to combustor primary zone.
Air flow routing characteristic of aero-engine combustors: Mixing jets downstream of primary zone.
Optional extended optical access combustor: Slightly reduced access to primary zone, wide access to mixing zone, additional access through windows in exit nozzle flange.

Applicationss:

Investigation of the reacting 2-phase flow field of aero-engine air-fuel nozzles at realistic operating conditions (air inlet temperature up to 850K, thermal load up to 1 MW) using advanced optical measurement techniques focussing on: 

• air flow field
• liquid fuel atomization
• air-fuel (spray and vapour) mixing
• flame stabilization / lean extinction
• combustion instabilities (optional forced excitation)
• pollutant formation / abatement
• Test rig specs
