Lean-burn combustion is one of the key technologies which can contribute to the reduction of future aero-engine emissions. Two principle candidate designs are currently proposed for lean-burn combustion systems, of which lean direct injection (LDI) combustion may emerge as the future mainstream lean-combustion technology. For low emission LDI combustion, the design of the fuel injector is crucial. This work therefore aimed at establishing design rules for future LDI combustion systems and, LDI injectors in particular. A novel low TRL multi-sector water flow facility has been developed. This three-injector facility introduced more aerodynamically representative boundary conditions to a water flow environment, thus increasing flow fidelity. In addition, the test facility has been designed to allow a variable injector pitch spacing. Three spacings could be realised. A stereo PIV system has subsequently been integrated to measure the flow. The modular design of the facility furthermore offers ample opportunity for future low TRL LDI combustion system research.
