11. Large Eddy Simulation of Turbulent Reactive Flows under HCCI Engine Conditions
Sammanfattning : Large Eddy Simulation (LES) modeling is developed to study homogeneous charge compression ignition (HCCI) combustion under different engine operation and mixture conditions, including real engine configurations and generic test cases. A previously developed HCCI model has been validated by comparing the simulation results with engine experiments. LÄS MER
12. A Study of Mach 0.75 Jets and Their Radiated Sound Using Large-Eddy Simulation
Sammanfattning : Large-Eddy Simulations (LES) of a compressible nozzle/jet configuration have been carried out. Two jets were simulated, an isothermal jet and a jet with a higher temperature than the surrounding air. The Mach number was in both cases 0.75 and the jet Reynolds number was 50,000. LÄS MER
13. A Combustion Concept for Future Heavy-Duty Diesel Engines
Sammanfattning : The Diesel engine has been intensively developed by manufacturers and researchers since 1892, when it was invented. However, the direction of its development has shifted in recent years.Environmental issues are becoming increasingly important in our society, prompting more efforts to be put into making the engines cleaner.

14. A representative interactive linear-eddy-model (RILEM) for simulating spray combustion
Sammanfattning : Engine development aims at reducing pollutant emissions (e.g. NOx , soot,UHC) while maintaining high efficiencies. Detailed experimental resultsin combination with precise numerical predictions are of great importancein order to develop combustion systems for new clean and efficient inter-nal combustion engines.

15. Transient Spray Mode Fuel Injection
Sammanfattning : This research examines the pivotal role of transient fuel spray in internal combustion engines, primarily focusing on their influence on dual-fuel (DF) engines. In the case of dual-fuel (DF) engines functioning in a gas mode, the controlling of the primary fuel’s ignition is usually managed through the direct injection of liquid pilot fuel. LÄS MER
