Virginia Tech, with support from NASA-Langley, has acquired high-quality turbulence model validation data for three-dimensional smooth-body flow separation. The geometry, called the BeVERLI Hill (Benchmark Validation Experiments for RANS and LES Investigations), has been studied at subsonic Reynolds numbers between 250k and 650k based on the hill height. Experimental data have been obtained for the hill at nominal zero, 30, and 45 degree orientations and includes extensive oil flow visualizations, surface pressures, skin friction via oil film interferometry and laser Doppler velocimetry, and mean and fluctuating velocities using particle image velocimetry, laser Doppler velocimetry, and pitot-static rakes. Detailed boundary conditions and oncoming boundary layer data have also been measured.
