Collisional drift fluids and drift wavesFunded under: EAEC-FUSION 12C
This paper presents a derivation of collisional drift-fluid equations by a new method which guarantees and enables the proof of energy conservation laws and total angular momentum. This method also leads to a law for energy dissipation for cases in which the dissipated energy does not remain in the plasma as thermal energy. The method consists of consideration of single particle motion in drift approximation, obtaining from the single particle Lagrangian, the Lagrangian for dissipationless fluids in drift approximation with isotropic pressures, and introduction of dissipative terms such as resistivity, thermal forces, viscosity, heat conductivity and energy transfer between the different particle species.
