Extracting a stochastic model for predator-prey dynamic of turbulence and zonal flows with limited data
J. C. Huang, Z. S. Qu, R. Varennes +6
Understanding the interaction between turbulence and zonal flows is critical for modeling turbulence transport in fusion plasmas, often described through predator-prey dynamics. Ho…
