Detailed Description

Transient conduction into quiescent liquid. A lower bound, and the default.

Args:
    enhancement: Multiplier on the conduction flux, 1.0 for pure quiescent
        conduction. Free convection and interfacial motion make the real
        value larger; this is where a *fitted* number from a cold-flow test
        goes, and it is deliberately a single dimensionless factor with an
        obvious meaning rather than a tuned coefficient with none.

◆ heat_total()

float feedtwin.vessels.collapse.ConductionCollapse.heat_total	(		self,
		float	area,
		float	gas_temperature,
		float	liquid_temperature,
		LiquidThermal	liquid,
		float	elapsed )

Cumulative heat [J] after ``elapsed`` at constant area and ΔT.

The closed-form integral of :meth:`heat_rate`. Not used by the
integrator -- area and temperatures both move -- but it is what the
model is validated against, and what answers "roughly how much does
this cost me over a 5 s burn" without running anything.
