Global drift-fluid model in a cylinder geometry.
The CELMA-model is a global drift-fluid model for modeling plasma turbulence in a linear device with constant magnetic field. The model describes the spatio-temporal evolution of the density, modified vorticity, momentum-density and current. It assumes isothermal electrons and cold ions, and does not use the Boussinesq-approximation. The derivation of the model can be found in the Derivation-part, and set of equations can be found under 5.6 The set of equations here.
The CELMA-code is written using the BOUT++-framework, and contains:
python3
.Jupyter-notebooks
for derivation of operators not already in the BOUT++ framework.Add-ons to the BOUT++ framework is documented using doxygen.
