Abstract
The aim of this study is to clarify the statistical properties of a plane jet diffusion field in liquid. The velocity and dye concentration have been measured by the LDV and the light absorption method. It was found that the downstream variation of square of reciprocal mean velocity on the jet axis and the half width of the jet vary linearly with downstream direction. It is ascertained that statistical properties of the present plane jet show good agreements with past other researcher's data.
