Experimental investigation of turbulent flow in a channel with flat upper wall and wavy lower wall using a particle image velocimetry technique is presented. The mean flow and turbulent characteristics in both the developing region and fully periodic region over the wavy wall were examined. It was observed that the flow characteristics become fully periodic after the eighth wave. The results also showed that the separation and reattachment points within the developing region and fully periodic region are similar. Detailed investigation of the flow field in the fully periodic region was examined using contour plots and one-dimensional profiles of the mean velocities, mean spanwise vorticity, streamwise and wall-normal turbulence intensities and Reynolds shear stress.
