Abstract: This paper describe the results of the experiments which were carried out to observe the situation of the steady streaming caused by the influence of the bottom and side walls boundary layers of standing waves. The steady streaming was observed visually using the dye tracers of Potassium permanganate (KMnO_4). It was found that there was a highly three dimensional flow structure in the steady streaming and the flow pattern was extremely completed. The wave flume used in this experiments has similar sizes of the width and depth. Therefore the side wall boundary layers affect to the streaming as much as the bottom boundary layer does. To explain the three-dimensional flow structure of the steady streaming the side wall boundary layer was analyzed by use of the boundary layer theory.
