Impact of ion-electron collisions on nonlocal ion heat conduction, viscous stress, and diffusion
Nicholas Mitchell, David Chapman, Grigory Kagan
By applying a first-principles reduced kinetic method, this work demonstrates the impact of ion-electron collisions on ion transport for strongly inhomogeneous plasmas in the nonlo…
A First-Principles Closure for Nonlocal Magnetized Transport
Nicholas Mitchell, David Chapman, Grigory Kagan
A reduced kinetic method (RKM) for describing nonlocal transport in magnetized plasmas is derived from first principles and considered in a 1D3V geometry. Unlike standard nonlocal…
Nonlocal current-driven heat flow in ideal plasmas
Nicholas Mitchell, David Chapman, Grigory Kagan
Electron heat flux is an important and often dominant mechanism of energy transport in a variety of collisional plasmas in a confined fusion or astrophysical context. While nonloca…
A reduced kinetic method for investigating non-local ion heat transport in ideal multi-species plasmas
Nicholas Mitchell, David Chapman, Christopher McDevitt +2
A reduced kinetic method (RKM) with a first-principle collision operator is introduced in a 1D2V planar geometry and implemented in a computationally inexpensive code to investigat…
