1315 側壁面に再付着する放射状噴流に関する研究

抄録

This study is concerned with the temporal and spatial structure of a radial jet which reattaches on the side wall. Fluctuating pressure correlations and pressure-velocity correlations were measured to clarify the unsteady flow characteristics. On the sidewall, there exist two dominant frequencies of fluctuations and the higher frequency fluctuation convects to down stream at 60% of the maximum velocity of the jet. Furthermore, it seems to propagate from upper side to the wall side.
