This paper concerns an experimental study of a rectangular jet with a sidewall that the jet reattaches on it. Aspect ratio of the rectangular jet is 18 and three types of end wall conditions are examined, i. e. with end walls on both sides, with an end wall on one side, and without an end wall. Flow behavior has been studied by means of flow visualization by an oil film method and velocity measurement by a hot wire probe. Oil film on the sidewall shows three-dimensional behavior near the end of the jet but there exists two dimensional flow region near the center region of the jet. Reattaching region and reattachment length are shown and the latter is found to be different from the case of two-dimensional jet.
