RISExperimental Study on Effects of Nozzle Hole Geometry on Achieving Low Diesel Engine Emissions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three injectors with different nozzle geometries were tested in a multicylinder diesel engine with a high-pressure common-rail injection system. Various injection pressures were tested along with ...
Modeling Diesel Spray Flame Liftoff, Sooting Tendency, and NOx Emissions Using Detailed Chemistry With Phenomenological Soot Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A detailed chemistry-based CFD model was developed to simulate the diesel spray combustion and emission process. A reaction mechanism of n-heptane is coupled with a reduced NOx mechanism to ...
Comparisons of Diesel PCCI Combustion Simulations Using a Representative Interactive Flamelet Model and Direct Integration of CFD With Detailed Chemistry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Diesel engine simulation results using two different combustion models are presented in this study, namely the representative interactive flamelet (RIF) model and the direct integration of ...
Development of a Semi-implicit Solver for Detailed Chemistry in Internal Combustion Engine Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An efficient semi-implicit numerical method is developed for solving the detailed chemical kinetic source terms in internal combustion (IC) engine simulations. The detailed chemistry system forms ...
