The confinement performance of a magnetically confined plasma depends on the particle and heat transport due to microscopic turbulence generated in the plasma. In this topic, we will perform numerical simulations of plasma turbulence based on a simplified model of magnetized plasma turbulence called the Hasegawa-Wakatani equation. In addition, we will analyze nonlinear interactions that give rise to complex turbulent phenomena by using Fourier analysis and network visualization. Let’s join us to experience running numerical simulations and analyzing data using a computer and think together about the complex interactions among eddies, waves, structures, and fluctuations in plasma turbulence.
