Comparison of hydrodynamic and semi-kinetic treatments for plasma flow along closed field lines Hydrodynamic and semi-kinetic treatments of plasma flow along closed geomagnetic field lines are compared. The hydrodynamic treatment is based on a simplified moment set of transport equations as the equations for the heat flows are not solved; the heat flows are treated heuristically.

  A new dynamic fluid‐kinetic model is developed for investigating the plasma transport along a closed magnetic flux tube in the plasmasphere by coupling the field line interhemispheric plasma (FLIP) model with a generalized semikinetic (GSK) model.   This treatment results in a quasi-one-dimensional description of the plasma where the plasma properties vary along a magnetic field line and the plasma is constrained to a certain volume by a magnetic wall. An example of the resulting steady state, integrated, continuity equation is shown below: (13) n u B = c o n s t a n t. Both hydrostatic and nonhydrostatic numerical models were developed using Delft3D‐Flow to predict the 3D flow field in a reach of Stillwater Creek in Ottawa, Canada. An acoustic Doppler velocimeter was employed to measure the 3D flow field at a section in a sharp bend of the simulated river at two flow . In this paper, the performance of hydrostatic versus nonhydrostatic pressure assumption in the three‐dimensional (3D) hydrodynamic modelling of a tortuously meandering river is studied. Both hydrostatic and nonhydrostatic numerical models were developed using Delft3D‐Flow to predict the 3D flow field in a reach of Stillwater Creek in Ottawa.

Hydrodynamic Effects in Plasma, Combustion and Astrophysics Due to the Archimedes force, potential energy stored in the heavy plasma is transformed into kinetic energy of the flow. The gravitational field may be real or "effective" like in inertial confined fusion, where laser-heated light plasma compress and accelerated the heavy target.   When the magnetic field is strong, magnetic tension, with enhanced field strength due to the KH instability, reacts back to the flow K.

In the present paper, the functional integration method is applied to a system of Fermi particles with Coulomb interaction (plasma) in a magnetic field. Interaction is taken into consideration by introducing a complementary Bose field. An expression for the hydrodynamic-effect functional is derived by integration over 'fast' Bose fields.
