SOOT FORMATION WHILE OPERATING A DIESEL POWER UNIT

Three-Dimensional Modeling of Combustion Process, Soot and NOx formation In a Direct-injection Diesel Engine

This paper is presented to study the combustion process and emissions in a direct injection diesel engine. Computations are carried out using a three-dimensional model for flows, sprays, combustion and emissions in Diesel engines. Interactions between combustion and emissions with flow field are considered and it is shown that soot mass fraction increases at regions with low turbulence inten...

Soot Formation within Conventional and Low Temperature Diesel Combustion

The soot formation processes of conventional and low temperature diesel combustion were investigated by a newly developed Forward Illumination Light Extinction (FILE) soot measurement technique in a constant volume spray chamber. The FILE technique has the capability to obtain two-dimensional time-resolved quantitative soot measurements. For diesel combustion at conventional ambient condition, ...

Extinction-based Imaging of Soot Processes over a Range of Diesel Operating Conditions

Soot Modeling in Diesel Engine

This paper presents an advanced version of the original software developed by the author in order to simulate the combustion in the Diesel engines, focusing on simulate soot formation. Complex kinetic mechanisms are need for realistic modeling of shoot formations, but this is applicable only for simple flame computations (e.g. one dimensional, laminar, etc.). For real turbulent flame calculatio...

Diesel soot combustion ceria catalysts

This review article summarizes the contents of the keynote lecture with the same tittle presented at the 7 th edition of the International Conference on Environmental Catalysis hold in Lyon (France) in September 2012. Different aspects of the ceria-catalyzed Diesel soot combustion reactions have been critically discussed, such as the high catalytic activity of ceria for Diesel soot combustion i...
