Flow and combustion in disc and pent-roof SI engines [PDF]

open access: yes, 2006
Reported in this thesis is a study of combustion in a disc-shaped combustion chamber spark ignition engine, and in-cylinder flow and combustion in an idealised pent-roof spark ignition engine. Both engines were skip fired, to remove residuals and ensure

Laser–plasma interactions for fast ignition [PDF]

open access: yesNuclear Fusion, 2014
In the electron-driven fast-ignition approach to inertial confinement fusion, petawatt laser pulses are required to generate MeV electrons that deposit several tens of kilojoules in the compressed core of an imploded DT shell. We review recent progress in the understanding of intense laser plasma interactions (LPI) relevant to fast ignition.

Study of the length and influencing factors of air plasma ignition time

open access: yesOpen Physics, 2022
When a high-energy laser acts on a film surface, plasma flashes of both the air and film can be generated simultaneously. However, when the conventional plasma flash method is used to identify thin film damage, there is a misjudgment problem caused by ...

Possible explanations for different surface quality in laser cutting with 1 micron and 10 microns beams [PDF]

open access: yes, 2012
In laser cutting of thick steel sheets, quality difference is observed between cut surfaces obtained with 1 micron and 10 micron laser beams. This paper investigates physical mechanisms for this interesting and important problem of the wavelength ...

Experimental investigations into high-altitude relight of a gas turbine [PDF]

open access: yes, 2008
This thesis describes experiments to investigate high-altitude relight of a lean direct injection (LDI) combustor. The features that make LDI technology less polluting in terms of NOx compared to conventional combustors are expected to impede relight ...
