Renormalisation Group Analysis of Turbulent Hydrodynamics

Figure 10

Fixed point of an unphysical model system, as found by use of the shooting method. Shown is the flow in the two-field interaction 𝜆₂ and the four-field interaction 𝜆₄. The attractive direction goes to the upper right and lower left corners of the diagram, and the other two directions are repulsive.
