Kinetic discretization of one-dimensional nonlocal flow models

نویسندگان

چکیده

We show that one-dimensional nonlocal flow models in PDE form with Lighthill-Whitham-Richards flux supplemented appropriate in- and out-flow terms can be spatially discretized a finite volume scheme to obtain formally kinetic physically meaningful reaction graph structure. This allows the utilization of theory chemical networks, as demonstrated here via stability analysis model circular topology. further propose an explicit time discretization Courant-Friedrichs-Lewy condition ensuring many advantageous properties scheme. Additional characteristics, including monotonicity total variation diminishing property are also discussed.

A nonlocal discretization of fields

A nonlocal method to obtain discrete classical fields is presented. This technique relies on well-behaved matrix representations of the derivatives constructed on a non–equispaced lattice. The drawbacks of lattice theory like the fermion doubling or the breaking of chiral symmetry for the massless case, are absent in this method.

One-dimensional models for blood flow in arteries

In this paper a family of one-dimensional nonlinear systems which model the blood pulse propagation in compliant arteries is presented and investigated. They are obtained by averaging the Navier-Stokes equation on each section of an arterial vessel and using simplified models for the vessel compliance. Different differential operators arise depending on the simplifications made on the structura...

On Electro-kinetic Fluids: One Dimensional Configurations

Electro-kinetic fluids can be modeled by hydrodynamic systems describing the coupling between fluids and electric charges. The system consists of a momentum equation together with transport equations of charges. In the dynamics, the special coupling between the Lorentz force in the velocity equation and the material transport in the charge equation gives an energy dissipation law. In stationary...

Nonlocal damping of helimagnets in one-dimensional interacting electron systems

We investigate the magnetization relaxation of a one-dimensional helimagnetic system coupled to interacting itinerant electrons. The relaxation is assumed to result from the emission of plasmons, the elementary excitations of the one-dimensional interacting electron system, caused by slow changes of the magnetization profile. This dissipation mechanism leads to a highly nonlocal form of magneti...
