Abstract
The authors research the jet from a two-dimensional nozzle which has a lip-plate, especially concerning the effect of the lip-plate length of the nozzle. Experiments are conducted at a Reynolds number of 6000. The aspect ratio of the nozzle exit is 300, and the lip-plate length is 0,2h and 3.3h, where h denotes the height of the nozzle. Using a hot-wire anemometer, the authors show mean-velocity and turbulence-intensity profiles. And, using glycol smoke, the authors visualise the flow from the nozzle, and get quantitative information by a PIV technique.
