Ion closure theory for high collisionality revisited

Journal Article Ji, Jeong-Young ; Held, Eric D. - Physics of Plasmas

According to analytical calculations of the ion collision operator, the ion-electron collision terms could be larger than the ion-ion collision terms. In the previous work [J.-Y. Ji and E. D. Held, Phys. Plasmas 20, 042114 (2013)], the ion-electron collision effects are diminished by the ion temperature change terms introduced from unlikely assumptions. In this work, the high-collisionality closures for ions are calculated without the temperature change terms. The ion-electron collision terms significantly modify existing closure coefficients.

Closure and transport theory for high-collisionality electron-ion plasmas

Journal Article Ji, Jeong-Young ; Held, Eric D. - Physics of Plasmas

Systems of algebraic equations for a high-collisionality electron-ion plasma are constructed from the general moment equations with linearized collision operators [J.-Y. Ji and E. D. Held, Phys. Plasmas 13, 102103 (2006) and J.-Y. Ji and E. D. Held, Phys. Plasmas 15, 102101 (2008)]. A systematic geometric method is invented and applied to solve the system of equations to find closure and transport relations. It is known that some closure coefficients of Braginskii [S. I. Braginskii, Reviews of Plasma Physics (Consultants Bureau, New York, 1965), Vol. 1] are in error up to 65% for some finite values of x (cyclotron frequencymore »« less

Closure theory for high-collisionality multi-ion plasmas

Journal Article Ji, Jeong-Young - Plasma Physics and Controlled Fusion

A general formalism is developed to construct and solve a system of linearized moment equations for parallel and perpendicular closures in high-collisionality plasmas. It is applicable for multiple ion species with arbitrary masses, temperatures, charges, and densities. The convergence of closure coefficients is evaluated by increasing the number of moments from 2 to 32 for scalar, vector, and rank-2 tensor moments. As an example, the complete set of closure coefficients for a deuterium-carbon plasma over the entire Hall parameter range is presented. Furthermore, the closure coefficients at various temperature ratios show that the one-temperature closure coefficients can differ significantly frommore » the two-temperature coefficients.« less

Revisited neoclassical transport theory for steep, collisional plasma edge profiles

Journal Article Rogister, A - Physics of Plasmas; (United States)

It is shown that existing neoclassical theories in the high collisionality regime are inadequate to describe the edge plasma, where the gradient length scales are of the order of (only) a few centimeters (the edge'' is defined here in relation to the neutrals ionization depth). Gyrostresses indeed modify considerably the continuity, energy, and parallel momentum equations if, as is usually the case, [Lambda][sub 1][equivalent to][nu][sub [ital i]] ([ital qR])[sup 2]/[Omega][sub [ital i]L][sub [psi]] [ital r] is not negligible compared to unity ([ital L][sub [psi]]=[ital L][sub [ital N]], [ital L][sub [ital T]], [ital L][sub [ital V]], where, e.g., [ital L][sub [italmore »« less
