Abstract

It is necessary to know the concentration field of fuel spray or jet because the combustion process strongly depends on it. Recently, the planar laser induced fluorescence (PLIF) measurement has been often used to clarify the two-dimensional concentration field. In this study, diacetyl was used as a fluorescence tracer. At first the basic characteristics of fluorescence were discussed. Next, the PLIF measurement was applied to investigate the concentration distribution of a transient hydrogen jet. Each jet shows a different configuration and concentration distribution, although the averaged jet shows axisymmetric results. The fuel concentration was also measured in the flame jet.
