Adverse Pressure Gradient Boundary Layer Experiments Using Synchronized PIV and a Hot Wire Anemometry Rake*

This is the first report of an adverse pressure gradient turbulent boundary layer experiment performed in Laboratoire de M\'{e}canique de Lille, LML, wind tunnel which is of 20 meter in length. The adverse pressure gradient was created by means of a bump of 30 cm height. The thickness of the boundary layer was about 30 cm and Reynolds number based on momentum thickness, Re$_{\theta}$, was 30 000 for 10 m/s external free stream velocity. A hot wire rake of 143 probes synchronized and simultaneously sampled together with 2 stereo PIV systems in the wallnormal-spanwise (YZ) plane, 1 cm upstream of the wires plane, and 1 stereo PIV system to record in the streamwise-wallnormal (XY) plane. One high repetition PIV system was used in streamwise-spanwise (XZ) plane with sampling frequency of 3000 VF/s and also at a slower rate simultaneously with hot wire signal.
