Three components of mean velocities and wall static pressure have been measured in swirling flows through a circular-sectioned 90°bend with a curvature radius ratio of 4.0 under the Reynolds number of 60000. The complicated correlation between internal flow behavior and wall pressure distribution has been clarified from a region of upstream straight pipe through a bend to a down-stream one. Also, the shift of axial flow, the movement of the swirl center and the streamwise decay of swirl intensity have been investigated.
