The development of the turbulent flow field inside a spark ignition engine is examined by
large-eddy simulation (LES), from the intake flow to the tumble break-down. Ten consecutive …

In the pursuit to improve thermal and fuel efficiencies of internal combustion engines,
various engine designs and configurations have been developed over recent years. Since …

Ammonia is a promising future energy carrier because of its carbon-free nature and high
volumetric energy density compared to hydrogen. However, implementing ammonia as a …

Understanding, modeling, and reducing the cycle-to-cycle variability (CCV) of combustion in
internal combustion engines (ICE) is a critical challenge to design engines of high efficiency …

In this paper, we compare the capabilities of two open source near-wall-modeled large eddy
simulation (NWM-LES) approaches regarding prediction accuracy, computational costs and …

The objective of this study is an improved understanding of the three-dimensional in-cylinder
flow and its influence on cycle-to-cycle variations in a fired, direct-injection, spray-guided …

The recent several years we developed the Scheimpflug lidar method. We combined an
invention from the 19 th century with modern optoelectronics such as diode lasers and …

The increasing availability of high-performance computing resources will allow scale-
resolving simulations such as large eddy simulations to be used instead of unsteady …

This experimental study investigates the flame-initiation period variability in the spark-ignited
homogeneous charge third-generation transparent combustion chamber optical engine. The …

Abstract Direct Numerical Simulation (DNS) is carried out to investigate flow and heat
transfer (passive scalar) over rough surfaces extracted from microscopy of combustion …
