The purpose of this study is to make clear the characteristics of a wall attachment device. The experiments on flow visualization have been made using this device with no control ports and one output port closed at Reynolds number 10 4. The tracer method was used to visualize flow of water in the device and its flow pattern was photographed.
From these photographs, the stream line, equi-vorticity line and velocity distribution were obtained using image processing technique.
