However, in the PSDW, the holes are hopping on the square lattice, as shown in44 , the microscopic origin of the drag is due to the correlated character of hopping transports of the vacancies between the active and passive layers, it leads to a very large drag.

We wish to model a polluant evolving by two mechanisms: a passive transport by the velocity field, and collisions with the other fluid particles modeled by random centered and independent increments {(αn , βn ) ∈ Z × Zd , n ∈ N}, independent of the velocity field.

The various terms that may enter into defining the time-derivative are divided into “source” terms Si , terms that are local in some sense (e.g., the pressure gradient) and “transport” terms Ti , terms that describe advection (e.g., the terms describing the passive transport of momentum or energy with the flow).
General Relativistic MHD Jets
Hydraulic, tracer, and geophysical measurements of transport parameters will be made during cavern enlargement, and instrumentation arrays will be installed in the finished cavities to monitor the long-term passive response in the stable zone surrounding the detectors.

As a first step we perform a test of passive cosmic ray transport along the magnetic field, which is directed along the x-axis, assuming K⊥ = 0 and a static medium, i.e v = 0.

The passive transport means that the cosmic ray gas has no dynamical influence onto the motion of thermal gas.

The difference between the passive and active cosmic ray transport is remarkable.

In order to check the presented method we compared results of the diffusive passive transport of cosmic rays with analytical solutions of the diffusion equation.

Thus, conventional wisdom leads to considering the magnetic field as dynamically irrelevant—a passive contaminant simply frozen into the background fluid and transported by purely hydrodynamic motions.
Saturation of the Magnetothermal Instability in Three Dimensions
However, in ideal MHD, due to ideal Ohm’s law, the magnetic field undergoes a passive transport by the fluid velocity and its topology is preserved.
