Anomalous transport induced by nonhyperbolicity

Anomalous Transport induced by Sheath Instability in Hall Effect Thrusters

It is well recognized to ascribe the anomalous cross-field conductivity inside Hall-effect thrusters to fluctuation-induced transport due to gradient-driven instabilities (Rayleigh or electron drift) and to electron-wall interaction (near-wall conductivity). In this contribution we have performed a 2D(r,θ) Particle-in-Cell (PIC) model showing the possibility of another mechanism inducing azimut...

Anomalous mixing and reaction induced by superdiffusive nonlocal transport.

Spatially nonlocal transport describes the evolution of solute concentration due to mass transfer over long ranges. Such long-range mass transfer, present in many flow situations, changes the character of mixing and consequent chemical reactions. We study mixing in terms of the scalar dissipation and reaction rates for mixing-limited equilibrium reactions, using the space-fractional advection-d...

Anomalous ion heating from ambipolar-constrained magnetic fluctuation-induced transport

A kinetic theory for the anomalous heating of ions from energy stored in magnetic turbulence is presented. Imposing self-consistency through the constitutive relations between particle distributions and fields, a turbulent Kirchhoff’s Law is derived that expresses a direct connection between rates of ion heating and electron thermal transport. This connection arises from the kinematics of elect...
