Knocking combustion research is crucially important because it determines engine
durability, fuel consumption, and power density, as well as noise and emission performance …

Knock combustion is one of the primary factors limiting thermal efficiency improvement in
spark ignition (SI) engines. After a century of research, scholars have made significant …

In this paper, a computational study was performed using a combination of several
numerical tools to better understand the limiting aspects of combustion in a passive pre …

Even in the laminar regime, lean H 2-air flames are prone to intrinsic Thermo-Diffusive (TD)
instabilities which contribute to flame acceleration. Applying the Thickened Flame (TF) …

Abstract The Thickened Flame (TF) model is a widely used approach for Large Eddy
Simulation of premixed flames. It is based on a “mapping” transformation where all …

Engine knock and super-knock have become the main barriers to significantly improving
engine thermal efficiency. To further study the nature of the abnormal combustion, this work …

High compression ratio natural gas engine (NGE) is prone to knock at high load, which
aggravates the thermal load of piston. Therefore, accurately evaluating the piston thermal …

The present work investigates the interaction of the turbulent flame and shock wave as well
as the end-gas autoignition in a newly designed constant volume combustion chamber …

Pollutant regulations and fuel consumption concerns are the driving guidelines for increased
thermal efficiency and specific power in current internal combustion engines. The …

In this paper, the unsteady behaviour of a compression-ignited (CI) engine combustion
chamber is studied by analysing the results of a Computational Fluid Dynamics (CFD) model …
