摘要: We consider a two-color formaldehyde PLIF thermometry scheme using a
wavelength-switching injection seeding Nd:YAG laser at 355 nm. The 28183.5 cm-1
and 28184.5 cm-1 peaks of formaldehyde are used to measure low temperature
combustion zone. Using a burst mode amplifier and a high speed camera,
high-repetition rate (20 kHz) temperature field measurement is validated on a
laminar coflow diffusion flame and demonstrated on a turbulent confined jet in
hot crossflow flame.
