Towards greener shipping

(10-01-2022) In his PhD, Haohan Li is looking for tools to make diesel engines of ships more ecological.

More than 90% of the world's freight is carried by ships, which are mainly powered by diesel engines. Optimisation of fuel injection, atomisation and the subsequent combustion process are therefore seen as one of the most effective means for diesel engines to meet emission standards without loss of engine performance.

"In my PhD, I specifically investigated fuel atomisation in diesel engines," says Haohan Li.

His PhD starts from previous experimental studies in the 'Ghent University Combustion Chamber I', which is an optically accessible combustion chamber for studying fuel atomisation, combustion and emissions. 

"I focused on modelling atomisation and used the OpenFOAM code (open source software) to study the atomisation process in diesel engines based on the Reynolds mean Navier-Stokes method (time-averaged equations of motion for fluid flow)," Haohan explains.

In his research, Haohan looked for differences between the diesel atomisation of ship engines and that of truck engines.

"The conclusions of my research lay the foundation for future research into atomisation of ship engines and contribute to greener shipping," Haohan concludes.
