CRETIN Sim — explosion / GW LightCell

chemiluminescent Na radiative transport · one kernel, two operating points · Zig→WASM, verified ↔ closed form 3.5e-6

Explosion (fireball history)

GW LightCell (steady)

Operating point

seed/contam n_Na₀

initial Na density (m⁻³). Methalox + NaCl, or contamination.

core T₀

initial fireball core temperature

final T

R₀ → Rmax

fireball grows to this radius (log m)

duration

n_Na (Cantera)

steady free-Na from speciation table

gas T

cylinder radius

designed device R (log m)

chemiluminescent boost

T_exc / T_kin. The one honest free knob (rate matrix, undirived). 1=LTE.

Light curve — emergent 589 power vs time

Steady emission

Composes the verified transport RTE solve. soot=0 (methalox doesn't soot, Cantera C₂H₂~1e-16). Line power in consistent-arb units (curve SHAPE + peak); absolute W needs photometry calibration. Quasi-steady snapshots, not coupled rad-hydro; t_exc_boost not yet derived. · cretin_sim.wasm
