| Workpackage 2: Combustion |
In Workpackage 2: Combustion, the very large spray combustion chamber facility conceived and built during I.P. HERCULES (A) will be commissioned, fully instrumented and the optical measurement infrastructure will be completed. The facility will be used to provide spatially resolved combustion process data under various configurations. These data will be used to validate sub models for combustion and pollutant formation, so as to formulate CFD codes able to predict in-cylinder processes of marine engines for various arrangements and advanced combustion concepts, including Low Temperature Combustion (LTC) and lean-burn gas combustion.
To obtain further validation data, transparent cylinder covers will be designed to be fitted on a large 2-stroke and a large 4-stroke experimental engines, to enable in-cylinder optical access and measurements of velocity field, flame geometry and heat transfer to be obtained under realistic operating conditions. These engines will be fully instrumented with high speed CCD and CMOS cameras, laser fuel spray visualization, IR surface temperature, transient ultra-fast exhaust species measurement equipment. The WP2 is also related to WP1: Extreme Parameter Engines and WP5: Exhaust Emission Reduction.
To obtain the very high charging pressures, wider operating range and higher efficiency beyond today’s state-of-art, requires further development in turbocharging systems.
The Workpackage 2 consists of two Tasks:
