Abstract Text:
BOUT++ is a versatile simulation code that has been applied to a wide range of problems related to edge MHD, boundary plasma turbulence, and transport. Over the past five years, significant progress has been made in many areas. In this conference, we will present an overview of the latest physics developments and simulation results. The topics covered will include, but are not limited to:
1) Simulations of tokamak boundary plasma turbulent transport in relation to setting the divertor heat flux width
2) Investigation of the impact of pedestal density gradient and collisionality on ELM dynamics
3) Exploration of the characteristics of grassy ELMs and their effect on the divertor heat flux width
4) Evaluation of the effects of radial transport on divertor power and particle flux width under different operational regimes in EAST
5) Fluid turbulence simulations of divertor heat load for ITER hybrid scenario
6) Numerical modeling of pedestal stability and broadband turbulence of wide-pedestal QH mode plasmas on DIII-D
7) Gyro-Landau-Fluid simulations of kinetic Peeling-Ballooning mode with bootstrap current
8) A new discovery of edge localized modes suppression using ICRH
9) Investigation of impurity migration patterns simulated by test particle module
10) Modeling of small tungsten dust grains in tokamak
11) Nonlinear simulations of BOUT++ for comparative study with measured 2D ELM structures in KSTAR H-mode plasma
12) Self-consistent simulation of transport and turbulence in tokamak edge plasma by coupling SOLPS-ITER and BOUT++
13) Extension of Landau-fluid closure to weakly collisional plasma regime
14) BOUT++ extension for full annular tokamak edge MHD and turbulence simulations
The results presented in this conference are expected to contribute to the advancement of our understanding of boundary plasma physics and aid in the development of fusion energy.
