An upward plane jet, impinging on the free surface of a shallow rectangular tank, oscillated in the absence of external periodical force. The frequency and the oscillation conditions were clarified. The position of the surface swelling created by the jet impingement, the pressure difference between the two sides of the jet and the flow velocity on the bottom near the jet inlet were measured, and their phase relation was examined. The fluttering jet was visualized using ink and the displacement was measured using an image-processing technique. The jet behavior was simulated well by a simplified model in which the distributed jet velocity was represented by the mean axial and transverse velocities.
