Talk: What is flame colour and what understanding it can give us?
July 25 @ 10:00 am - 11:00 am
Professor Yang Zhang
External Examiner for Bachelor of Engineering (Hons) Mechanical Engineering
What is a hydrocarbon flame colour and what kind of useful information can be derived by visualization and quantitative processing it will be presented. At the same time the less well understood hydrogen flame colour will also be discussed. Contrary to the misconception among even the well established combustion scientists that a hydrogen flame is colourless, a hydrogen flame can be very bright and colourful depending on the burning process. The exact mechanism is not well understood yet and it is worth of further investigation.
