The numerical calculation and the experiment of a wall attachment device have been performed in a turbulent flow field. In this calculation method, the flow field was divided according to the local Reynolds number into turbulent, transition and laminar flow regions, and a calculation method suitable for each region was applied. Then, the k-ε turbulent flow model was used for turbulent calculation. The experiments comprised velocity measurement using a 3-port Pitot tube and flow visualization by the tuft method. The calculation and experiment were carried out under the condition that the ratio of the control flow rate to the supply flow rate was 0 and 20%. These calculated results agreed well with the experimental results. The effects of the control flow exerted on the flow pattern, and the characteristics of the turbulent flow field in a wall attachment device were clarified.
