Compression Ramp Movies

These movies correspond to the computations described in: K. M. Porter and J. Poggie, "Selective Upstream Influence on the Unsteadiness of a Separated Turbulent Compression Ramp Flow," Physics of Fluids, Vol. 31, 016104, 2019. DOI: 10.1063/1.5078938

Cases

• Case 1: Fine grid 3.0e9 cells, run for 2.9e5 steps (Ue t / Lsep = 200)
• Case 2: Coarser grid, very long run 4.0e7 cells, run for 1.2e7 steps (Ue t / Lsep = 9000)

Movies

• combined_side_wall_case1.mp4: Grayscale indicates density field in center plane of computational domain. Orange contours indicate skin friction magnitude at no-slip wall. Case 1 results.
• skin_friction_case1_dt2.mp4: Contours of skin friction magnitude at no-slip wall for Case 1 calculations. Delta t = 2.0 between frames.
• skin_friction_case2_dt2.mp4: Contours of skin friction magnitude at no-slip wall for Case 2 calculations. Delta t = 2.0 between frames.
• skin_friction_case2_dt20.mp4: Contours of skin friction magnitude at no-slip wall for Case 2 calculations. Delta t = 20.0 between frames for 10x movie speed.
• skin_friction_case2_dt200.mp4: Contours of skin friction magnitude at no-slip wall for Case 2 calculations. Delta t = 200.0 between frames for 100x movie speed.
