抄録

The injection of a two-dimensional free jet into a stationary fluid results in the formation of two parallel vortex streets whose vortexes are located alternately when the Reynoldos number is determined by the velocity of the jet and the nozzle width Is In the range of 102-103.<BR>To study the behavior of such vortex street, we used milk as a tracer and recorded the pattern of the flow, i.e. the vibration, of two vortex street and the central axis of the Jet.<BR>Furthermore, we recorded the power spectrum of the pressure changes In the flow field using pressure sensors, and studied the behavior of the vibrating flow Jet field. In addition, assuming that the flow is that of an Ideal fluid, we represented the flow field using Euler's kinetic equation and a linear approximation equation of continuity, and demonstrated that the two parallel jet vibrated. We also present the vortex street generated by the parallel jet.
