RISLarge Eddy Simulation of an n Dodecane Spray Flame Under Different Ambient Oxygen Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An ndodecane spray flame was simulated using a dynamic structure largeeddy simulation (LES) model coupled with a detailed chemistry combustion model to understand the ignition processes and the quasisteady state flame ...
A Computational Investigation of Fuel Chemical and Physical Properties Effects on Gasoline Compression Ignition in a Heavy-Duty Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gasoline compression ignition (GCI) offers the potential to reduce criteria pollutants while achieving high fuel efficiency. This study aims to investigate the fuel chemical and physical properties effects on GCI operation ...
Piston Bowl Geometry Effects on Gasoline Compression Ignition in a Heavy-Duty Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A design optimization campaign was conducted to search for improved combustion profiles that enhance gasoline compression ignition in a heavy-duty diesel engine with a geometric compression ratio of 17.3. A large-scale ...
A Multicomponent Blend as a Diesel Fuel Surrogate for Compression Ignition Engine Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mixture of ndodecane and mxylene is investigated as a diesel fuel surrogate for compression ignition (CI) engine applications. Compared to neat ndodecane, this binary mixture is more representative of diesel fuel because ...
Evaluating Optimization Strategies for Engine Simulations Using Machine Learning Emulators
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This work evaluates different optimization algorithms for computational fluid dynamics (CFD) simulations of engine combustion. Due to the computational expense of CFD simulations, emulators built with machine learning ...
