The regular oscillation of an attached jet occurs when the jet squirts into a suddenly enlarged flow passage from the rectangular nozzle which is set lower than the passage, depending on the shapes of the nozzle, flow passage and jet velocity. This paper presents the condition which causes the oscillation and the relations between the oscillatory frequency and the various conditions such as passage dimensions or jet speed. The mechanism of oscillation is qualitatively explained from an observation of the oscillatory flow pattern and a measurement of the pressure.
