Fuel stratification to enable higher load operation of homogeneous charge compression ignition engines. The project aims to provide knowledge needed to solve a problem impeding the development of an efficient and clean engine concept known as homogeneous charge compression ignition. Fuel stratification using alternative fuels will be studied fundamentally and used to reduce the problematic rapid pressure changes that occur in these engines.
The stabilisation of lifted jet flames in hot oxidiser. The project will contribute fundamental insights on a crucial phenomenon in diesel engines: the detachment of the flame from the fuel nozzle, which strongly affects harmful emissions of nitrogen oxides (NOx) and particulates. Detailed numerical simulations will be used to reveal the mechanism of flame stabilisation, knowledge that will aid the development of cleaner engines.
