In this paper, by means of the numerical experiment, the laminar jet behaviour in an attachment fluidic device with small aspect ratio is investigated. The numerical solution for the three-dimensional, imcompressible, unsteady and viscid flow is calculated by solving the primitive Navier-Stokes equations by use of the predictor-corrector method. The results obtained can be summarized as follows : 1. In the case of smaller aspect ratio, the numerical solution can be obtained to the extent of the higher Reynolds Number. 2. Near the bounding plates more fluid flows into the separation bubble than that at midplane and then this flows toward midplane, and finally is entrained by the main flow. 3. The flow along the side wall, also, enters the bubble near the bounding plates. This results in a longer attachment distance near the bounding plates.
