The flow fields and the motions of vortices characterizing the pulsating jets were experimentally examined using both the smoke visualization method and the velocity measurement by a hot wire anemometer. The results of the velocity variation are found to agree with those of the flow visualization. The pulsating jets can be classified into three kinds of flow state; they are termed a row of puffs, a row of vortex rings in jet column mode, and a row of vortex rings in shear layer mode. In this paper, the puff was defined as a lump of fluid consisting of a leading vortex and a trailing jet following the vortex. The puff may be regarded as the state possessing the most fundamental features of a pulsating jet.
