AB In this work soot-oil visualization of separated flow is made and pressure fields are measured on the walls of transverse cavity with the depth and bottom width H=L=60 mm and relative extension S/L=3. At this the tilt angle of the front and back walls was varied φ = 90°, 80°, 70°, 60°, 45°, and 30°. Visualization was carried out at three velocities of the incident flow U=10, 20, 30 m/s and corresponding Reynolds numbers ReH = 3.9×104, 7.9×104, 1.2×105. Evolution of separated flow and vortex formation at different changes in the tilt angle of sidewalls and incident flow velocities was analyzed with the help of visualization. For comparison visualization was made in a triangular cavity of the same depth and extension. Results of visual observations are proved by measured distributions of static pressure over the cavity walls.
