Geodesic acoustic modes in a fluid model of tokamak plasma : the effects of finite beta and collisionality

, 2015
Starting from the Braginskii equations, relevant for the tokamak edge region, a complete set of nonlinear equations for the geodesic acoustic modes (GAM) has been derived which includes collisionality, plasma beta and external sources of particle ...

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Relation between porosity‐based and crystal‐based femtosecond laser‐induced nanogratings in oxide glasses

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Femtosecond laser irradiation in glass, under controlled conditions, can induce two types of nanogratings (NG): porous nanogratings (pNG) and crystal/glass nanogratings (cNG). While most glasses exhibit only one type, binary aluminosilicate glasses have shown both types of NG.

Demonstration Tokamak Power Plant [PDF]

Nuclear Technology - Fusion, 1983
A design study of a tokamak-based fusion demonstration reactor was carried out. The study focused on four critical design features: 1) current drive for steady-state operation, 2) impurity control and exhaust, 3) breeding blanket, and 4) reactor configuration and maintenance.

Magneto‐Thermal Assessment of Ferrofluid Flow in Corrugated Porous Domain With Rotating Cylinder for Nuclear Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This research presents a novel approach by combining magnetohydrodynamic (MHD) flow with ohmic heating to investigate the conjugate mixed convective transport of ferrofluid in a discretely heated, smooth/wavy‐walled, square‐shaped porous compartment featuring a clockwise spinning cylindrical body positioned at various locations.

On the impact of temperature gradient flattening and system size on heat transport in microtearing turbulence

Nuclear Fusion, 2023
Microtearing instability is one of the major sources of turbulent transport in high- β tokamaks. These modes lead to very localized transport at low-order rational magnetic field lines, and we show that flattening of the local electron temperature ...

Nonlinear Alfvén instability simulation and EP transport for ITER reversed shear (steady-state) and monotonic q-profile regimes

Nuclear Fusion
The nonlinear evolution and dynamics of energetic particle (EP) driven instabilities in both steady-state (reversed shear q-profile) and monotonic q-profile regimes of ITER are examined using the global gyro-Landau closure model FAR3d.
