Computations of Turbulent Premixed Flames Using Conditional Moment Closure
Lean premixed combustion is at present one of the most promising methods to reduce emissions and to maintain high efficiency in combustion systems. As the emission legislation becomes more stringent, modelling of turbulent premixed combustion has become an important tool for designing efficient and …

Turbulent combustion simulation in realistic gas-turbine combustors
… and efficient numerical modelling of turbulence combustion with an emphasis on an industrially representative Tay model combustor. This combustor retained all essential features of a modern aero-engine rich burn combustor and thus the turbulence combustion within this combustor is much more …

Large eddy simulation of a fuel-rich turbulent non-premixed reacting flow with radiative heat transfer
… (β- PDF) for the simulation of turbulent non-premixed reacting flow, in particularly for the predictions of soot and NO production, and to investigate the radiative heat transfer during combustion process applying Discrete Ordinates Method (DOM). LES seeks the solution by separating the …

Autoignition in turbulent two-phase flows
… Moment Closure (CMC) method for turbulent non-premixed combustion. The dissertation can be split in four different sections, with the content of each being summarized below. The first part of the dissertation introduces the equations that govern the temporal and spatial evolution of a …

CFD modelling and investigation of two-stroke dual-fuel marine engines with high pressure gas admission
… burning natural gas and pilot fuel to initiate combustion is an alternative, which can considerably reduce the engine environmental footprint. The application of the high pressure and direct injection of the natural gas can remarkably benefit the emissions. In order to understand in-depth the …

Novel Approach for Computational Modeling of a Non-Premixed Rotating Detonation Engine
… in time-scale required to resolve the combustion process and flow-field. The alternate two-dimensional analyses are generally modeled with perfectly premixed fuel injection and do not capture the effects of improper mixing arising due to discrete injection of fuel and oxidizer into the …
