Abstract
Vortex structure and bed pressure fluctuation in a plane impinging jet are investigated by the flow visualization and the pressure meseurement. For the visualization of the cross-sectional view, the laser illuminated fluorescent dye method were adopted. Observations by visualization make clear that a vortex structures hardly change by flow impingement. And the simultaneous observation of visualization and pressure shows that the movement of vortex explicitly contributed to the pressure fluctuation.
