An experimental study has been carried out for the turbulnt flow through a circular-sectioned 90°bend of a curvature radius ratio of 4.0 with inlet and outlet straight pipes attached. Three components of mean and fluctuating velocities were measured by the technique of rotating a probe with an inclined hot wire under a Reynolds number of 60000. The flow patterns of main and secondary streams, and Reynolds stress distributions in pipe sections are illustrated with figures, and explanations are added on the process of phenomena in the streamwise direction.
