RECYCLING_H

struct Recycling : public Component

#include <recycling.hxx>

Convert fluxes of species at boundaries

Since this must be calculated after boundary fluxes (e.g. sheath), it is included as a top-level component

Field3D density_source

Field3D energy_source

Recycling particle and energy sources for all locations.

Field2D is_pump

1 = pump, 0 = no pump. Works only in SOL/PFR

Field3D radial_particle_outflow

Field3D radial_energy_outflow

Radial fluxes coming from evolve_density and evolve_pressure used in recycling calc.

struct RecycleChannel

Public Members

std::string from

The species name to recycle.

std::string to

Species to recycle to.

BoutReal target_multiplier

Flux multiplier (recycling fraction). Combination of recycling fraction and species change e.g h+ -> h2 results in 0.5 multiplier

BoutReal sol_multiplier

BoutReal pfr_multiplier

BoutReal pump_multiplier

BoutReal target_energy

BoutReal sol_energy

BoutReal pfr_energy

Energy of recycled particle (normalised to Tnorm)
