The CFD Development of Non-premixed Dual Fuel Combustion Diesel Engine injected by High-pressure Gas in the Cylinder Chamber


High-pressure gas injection and non-premixed combustion of gaseous and liquid fuels in marine engine operating on the dual fuel mode is a quite new technology that can be effectively used for reducing the pollutant emissions from ships. Currently, there is no published theoretical method to represent the involved processes and NOx formation mechanisms of dual fuel engines. In this respect, the non-premixed dual fuel combustion model will be investigated with focus on the development of the two independent mixture fractions using the probability density function to decouple the turbulence and chemistry interaction. By comparing the engine cylinder pressure history and combustion characteristics obtained from the engine shop tests and literature, the developed method will be verified and proposed as a feasible solution of the complicated diffusive combustion processes occurring in marine engines operating on the dual fuel mode.
