Fig. 11From: Criteria of tracking vortex surfaces in turbulent-like flowsFurther close-up view of the evolution of the VSF isosurface with Vϕ=VΩ/16 in the region marked by the red box in Fig. 10 in case M1 (ηM=0.05). The color bar is the same as that in Fig. 9. Some vortex lines are integrated from points on the surfaceBack to article page
