- This page gives a short description of the physical models underlying the SIGLO series
of discharge modeling software.
|
|
|
- The codes in the SIGLO series are fluid models which solve numerically equations
representing electron and ion transport in a weakly ionized (collisional) plasma coupled
with Poisson's equation for the electric field in 1D or 2D cylindrical or rectangular
geometries.
|
|
|
- Charged particle transport is represented by moments of the Boltzmann equations:
continuity, momentum and energy equations (only the first two moments are used for ions).
The codes in the SIGLO series differ in their dimensionality and in the approximations
made for the ionization source term (which make each code suitable for a certain range of
conditions).

- SIGLO-RF : 1-D,
three-moment description of the electrons; ionization rate depends on the mean electron
energy.
|
 |
|
- SIGLO-2D : 2-D,
cylindrical, two- or three-moment description of charged particle transport coupled with
Poisson's equation; ionization depends on E/N or mean electron energy.

- SIPDP-AC
:
2D, rectangular, two-moment description of charged particle transport coupled with Poisson's
equation (fast semi-implicit integration) ; ionization depends on E/N.

SIPDP-3D
:
3D, rectangular, two-moment description of charged particle transport coupled with Poisson's
equation (fast semi-implicit integration, similar to SIPDP-AC) ; ionization depends on E/N.
