About this event
Accurate combustion simulations are indispensable to further advance the development of metal fuels and these require validation through experimental data. Currently the particle temperature can be measured reliably, but this is only half of the story. The concept of laser-induced fluorescence of molecular oxygen is therefore investigated to measure the other half: the temperature of the gas. This is not trivial, since excitation requires light in the deep ultraviolet (190 – 210 nm) and metal particles reflect laser light very efficiently, which obstructs part of the fluorescence signal. In this work, the operation and performance of the diagnostic technique is examined and improved, and it is investigated how measurements can be performed in iron flames effectively.
