RISThree-Dimensional Computational Fluid Dynamics Simulation and Mesh Size Effect of the Conversion of a Heavy-Duty Diesel Engine to Spark-Ignition Natural Gas Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With developing in computer technology, three-dimensional (3D) computational fluid dynamics (CFD) internal combustion (IC) engine simulations, which generally use reduced chemical kinetic mechanisms and simplified combustion ...
Numerical Investigation of Methane Number Effect on Combustion, Performance, and Emissions in a Heavy-Duty Spark Ignition Natural Gas Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In this study, the effects of methane number (MN) on the numerical conversion of a heavy-duty diesel engine to a spark ignition (SI) natural gas engine were investigated. A high-compression-ratio configuration ...
A Numerical Investigation Into the Effects of Equivalence Ratio and Exhaust Gas Recirculation on Performance and Operating Range in High Compression HCCI Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study investigates the performance of a high compression ratio engine converted to homogeneous charge compression ignition (HCCI) operation. A total of 24 case studies were conducted with φ = 0.22–0.29 and ...
