It is very important to clarify the structure and the behavior of the Coanda effect, which is one of the characteristics of the jet flow, from the viewpoint of the industrial applications such as a nozzle. In the former report, the structure of the Coanda effect was clarified by the experiment and its behavior was clarified by the numerical analysis. This paper clarifies the stabilization time and the adhesion situation of the jet flow by changing the offset ratio between the nozzle and the sidewall. And the shadowgraph similar to the experiment of visualization could be also obtained by the numerical analysis. Moreover this paper certified that the numerical analysis had the shock wave similar to the experiment of visualization.
