Numerical Solutions of Resistive Finite-Pressure Magnetohydrodynamic Equilibria for Non-Axisymmetric Toroidal Plasmas
Thu, Jan 30, 2025, 10:00 am – 11:00 am
Abstract: A hybrid spectral/finite-element code, NTEC, is developed to numerically solve the resistive finite-pressure magnetohydrodynamic equilibria in non-axisymmetric toroidal systems. The adopted approach integrates a hyperbolic parallel damping equation for pressure updating, along with a dynamic resistive relaxation for…

How Does Ion Temperature Gradient Turbulence Depend on Magnetic Geometry? Insights from data and machine learning.
Thu, Feb 13, 2025, 10:00 am – 11:00 am
Abstract: Magnetic geometry has a significant effect on the level of turbulent transport in fusion plasmas. Here, we attempt to understand this dependence using multiple machine learning methods and a dataset of > 200,000 nonlinear simulations of ion-temperature-gradient turbulence in diverse non-axisymmetric geometries. At…
