Variational Formulation of Macro-Particle Algorithms for Kinetic Plasma Simulations
A variational method is used to derive a self-consistent macro-particle model for relativistic electromagnetic kinetic plasma simulations. Extending earlier work [1], the discretization of the electromagnetic Low Lagrangian is performed via a reduction of the phase-space distribution function onto a collection of finite-sized macro-particles of arbitrary shape and discretization of field quanti...
متن کاملGrid-Free Electromagnetic Plasma Simulations
Basic plasma science plays an increasingly significant role in applications of importance to the United States Air Force. Many of these applications require a fully kinetic description in at least part of the domain. The most common approach is to use a fully Lagrangian framework, where the model is reduced to tracking the evolution of test particles in phase space. Of the many varieties, the m...
متن کاملA variational formulation of vertical slice models
A variational framework is defined for vertical slice models with three-dimensional velocity depending only on x and z. The models that result from this framework are Hamiltonian, and have a Kelvin– Noether circulation theorem that results in a conserved potential vorticity in the slice geometry. These results are demonstrated for the incompressible Euler– Boussinesq equations with a constant t...
متن کاملVariational formulation of macro-particle plasma simulation algorithms
Variational formulation of macro-particle plasma simulation algorithms" (2014). A variation formulation of macro-particle kinetic plasma models is discussed. In the electrostatic case, the use of symplectic integrators is investigated and found to offer advantages over typical generic methods. For the electromagnetic case, gauge invariance and momentum conservation are considered in detail. It ...
متن کاملEuler - Poincaré formulation of hybrid plasma models
Several different hybrid Vlasov-fluid systems are formulated as Euler-Poincaré systems and compared in the same framework. In particular, the discussion focuses on three major hybrid MHD models. These are the current-coupling scheme and two different variants of the pressurecoupling scheme. The Kelvin-Noether theorem is presented explicitly for each scheme, together with the Poincaré invariants...
