Application of Laser Ignition in Marine and Aero Gas Combustors
Based on the current effort to meet tightening emission laws, future gas engines are designed to operate under higher compression ratios and leaner fuel-air ratios. To reliably ignite the gas fuel-air mixture under such conditions, a new ignition concept is required since current spark plug has already reached its borders due to many reliability issues. Laser ignition has many potential advantages which makes it a viable replacement for spark plugs, but it is yet to be implemented in these combustors due to limited knowledge of its combustion and impact. My current project focuses on understanding the dynamics of a laser-ignited flame at the early development stage, its interaction with the flow field of varying gas composition and how this interaction leads to a stable or unstable flame.
In light of the High Court decision to force the UK government to publish its air quality plan by May 9th 2017, UCL Mechanical…Read more
