Two dimensional turbulence has the magnificent property to self organize in large structures unlike three dimensional turbulence that leads to disorganization. When strongly anisotropic flows are considered the flow has a hybrid behavior that is not yet understood. Varying the anisotropy turbulence displays phase transitions from a self-organizing state to disorganized state. The present project is going to investigate such phase transitions at different limits in order to understand the flow behavior close to the critical points. The work will be based on numerical simulations of the Navier-Stokes equations and the use of simplified theoretical models.
