The diverging channel was modelled in the closed type working section by fastening a displacement body above the flat plate that is parallel with the wind-tunnel axis. The angle of the channel expansion 11 degree induced the pressure gradient parameter K = from -0.16 to -0.28 with the flow velocity U0=30 m/s at the start of expansion, x=0. The height of the channel is 0.15 m at x = 0. FST was either natural 0.3 percent or amplified by turbulence generating grids/screens with turbulence levels up to 5 percent.
