Detailed Description

Native C++ two-temperature 0D plasma reactor (stateless per-eval evaluator).

Wraps the shared ReactorRHS (chemistry/Joule/exchange) with a composition-resolved CollisionModel and the constant-mass volume equation, exposing the per-eval conductivity and rhs that the Python driver (scipy + NRP circuit) calls. The state vector is

\[ y = [T_g,\, T_e,\, V,\, Y_0, \ldots, Y_{K-1}], \qquad \rho = \frac{\text{mass}}{V}. \]

With polytropic_index \( = \infty \) the volume is held constant ( \( dV/dt = 0 \)), matching the 1D channel's constant-volume assumption; a finite index activates the polytropic rarefaction model.

rhs()

void rizer::Plasma0DReactor::rhs	(	double	Tg,
		double	Te,
		double	V,

Writes dydt = [dTg, dTe, dV, dY_0..dY_{K-1}] (length 3 + K), where

\[ \rho = \frac{\text{mass}}{V}, \qquad \text{polytropic\_index} = \infty \implies \frac{dV}{dt} = 0 \]

(constant volume).

	Y	Species mass fractions [-], length nSpecies()
	E	Electric field [V/m]
	mass	Reactor mass [kg] (constant)
	p_ext	External pressure [Pa] (polytropic relaxation target)
	polytropic_index	Polytropic index [-] ( \( \infty \) => constant volume, \( dV/dt = 0 \))
[out]	dydt	[dTg/dt, dTe/dt, dV/dt, dY_k/dt] in [K/s, K/s, m^3/s, 1/s], length 3 + nSpecies()
