Flow structures passing through an inclined tube and inclined tube banks were investigared in the present study. Experiments were carried out using acrylic rectanglar water tunnel. Re is ranged from 2000 to 10000. Flow were visualized by minute particles and recorded by a high-speed video camera. The particle image velocimetry were carried out, and velocity fields are obtained. As a result, three typical regions of time-averaged streamwise velocity were observed in the wake region of an inclined tube. These velocity regions are considered to be caused by secondary flows that appeard in the wake region and both sides of the tube. Moreover, these secondary flows are considered to be caused by inclined vortex shedding.
