Abstract
From the experimental results of a reattachment flow issuing from a finite width nozzle having various aspect ratios, it is made clear that behaviour of the flow is influenced by nozzle shape, Reynolds number and initial turbulence intensity. As aspect ratio of the nozzle becomes smaller than 3, behaviour of the flow changes considerably, influenced by the side plates. The calculated results for a two-dimensional reattachment flow are not valid for such a flow. A new correction factor is introduced as a function of aspect ratio, offset ratio and Reynolds number. As the result, the reattachment distance of a flow having a small aspect ratio can be expressed by using this factor in a wide range of offset ratios, except very small ones.
