Concept of rapid and controllable combustion for high power-density diesel engines

Long Liu et al.

Summary: In recent years, there has been significant interest in reducing global carbon emissions, leading to stricter policies and regulations. For high power-density marine diesel engines, optimizing fuel consumption is difficult due to the large injection mass and little intake swirl. This article proposes a concept of rapid and controllable combustion to address this issue, which involves optimizing the combustion process based on the Sabathe-Miller cycle and determining controllable parameters through the evolution of in-cylinder spray.

Investigation of counter-rotating shock wave and wave direction control of hollow rotating detonation engine with Laval nozzle

Guangyao Rong et al.

Summary: This study investigates the counter-rotating shock wave and wave direction control in a hollow rotating detonation combustor with a Laval nozzle. The phenomenon and spatial distribution of the counter-rotating shock wave in the combustor are revealed using the in-house solver BYRFoam developed on the OpenFOAM platform. The study proposes a method of controlling the wave direction by reducing the inlet total pressure, which in turn controls the intensity of the counter-rotating shock wave. The study also investigates the mechanism of wave direction control and finds a positive feedback interaction between the counter-rotating shock wave and the fresh gas, leading to the evolution of reverse detonation waves.

Exploration of environmentally friendly marine power technology-ammonia/diesel stratified injection

Long Liu et al.

Summary: Ammonia is a promising carbon-free alternative fuel for reducing carbon emissions in marine engines. The study found that ammonia-diesel stratified injection technology can significantly reduce CO2 and NOx emissions, improve energy ratio, and meet future low-carbon emission regulations without the need for after-treatment. Increasing injection pressure and reducing pilot fuel proportion is the optimal solution for achieving high IMEP, low NOx, and carbon emissions.
