Large-eddy simulation of fuel injection and combustion in a direct-injection natural gas
engine was conducted. The influence of the fuel injection timing and ignition position was …

Prediction of in-cylinder flows and fuel-air mixing are two fundamental pre-requisites for a
successful simulation of direct-injection engines. Over the years, many efforts were carried …

Multiple injection strategies are commonly used in conventional Diesel engines due to the
flexibility for optimizing heat-release timing with a consequent improvement in fuel economy …

Given the importance of the fuel-injection process on the combustion and emissions
performance of gasoline direct injected engines, there has been significant recent interest in …

The paper focuses on the development of a mesh moving method based on non-conformal
topologically changing grids applied to the simulation of IC engines, where the prescribed …

Flame penetration into the top-land crevice of a combustion engine's cylinder is investigated
by large-eddy simulation (LES) and high-speed visualization experiments. This penetration …

Diesel combustion is a very complex process, involving a reacting, turbulent and multi-
phase flow. Furthermore, heavy duty engines operate mainly at medium and high loads …

Control of the combustion process in Spark-Ignition (SI) engines operated with extreme
dilution from exhaust gas re-circulation (EGR) represents one of the major limitations in the …

Deforming domains occur in many fields of computational fluid dynamics (CFD), such as
interface tracking, simulation of pumps and engines, and fluid/structure interaction. The …

The present paper describes and validates an efficient CFD implementation to replicate the
working fluid-dynamics of a real four-stroke internal combustion engine. To do this …
