An experimental investigation of turbulent flow over a single cavity in an asymmetric diverging channel is presented. Cavities of two different aspect ratios, w/h = 1 and 4, of height h = 6 mm were studied. The Reynolds number based on the approach freestream velocity and cavity height was Reh = 5000. Particle image velocimetry technique (PIV) was used to conduct detailed velocity measurements upstream of the cavity, inside the cavity and as far downstream of the cavity as x/h = 50. Mean velocity, turbulent intensities and Reynolds shear stress were obtained to document the effect of the cavity on the flow in the presence of adverse pressure gradient.
