Abstract : Objective: Find a reduced description for turbulence in tokamak plasmas
Method: Analysis of GYSELA simulation 3D output
What are turbulent vortices’ dynamics? How to reduce the description?
Results:
• Zonal flows act as toroidal motion, and zonal shear acts as radial motion
• Zonal shear yields stationary tilt of turbulent eddies
• Pressure-potential phase shift distribution is narrow, around quasi-linear value
• QuaLiKiz linear prediction in qualitative agreement with GYSELA simulation
