Measurement of inverse temperature gradient along a turbulent plane flame using an optical method

摘要

In order to measure the mean inverse temperature gradient along a plane flame, the latter is traversed by a laser beam. Our goal is to arrive at the mean inverse temperature gradient along the beam's path by examination of the dot projected on to a position probe by the beam after its having traversed the medium under study. A calculation model based on the Einstein-Fokker-Planck-Kolmogorov equation enables us-by monitoring of the final state (dot)-to arrive at a local diffusion coefficient. This latter will play an important part in calculation of the inverse temperature gradient.
