Experiments were conducted for 2D circular cylinders at Reynolds numbers in the range of 1.73 × 10 5 –5.86 × 10 5 . In the experiment, two circular cylinder models made of acrylic and stainless steel, respectively, were employed, which have similar dimensions but different surface roughness. Particu...
