Function Documentation

compute_film_cooling()

Dict[str, float] engine.pipeline.thermal.film_cooling.compute_film_cooling	(	float	mdot_total,
		float	mdot_fuel,
		Dict[str, float]	gas_props,
		FilmCoolingConfig	film_config,
			fuel_props )

Compute film cooling effectiveness and adjusted heat-flux factor.

Parameters
----------
mdot_total : float
    Total propellant mass flow [kg/s].
mdot_fuel : float
    Fuel mass flow [kg/s] (before allocating film fraction).
gas_props : dict
    Dictionary of hot-gas and geometry properties (Tc, rho, velocity, h_hot_base,
    chamber length, circumference, hot surface area, etc.).
film_config : FilmCoolingConfig
    Film cooling configuration object.
fuel_props : FluidConfig
    Fuel fluid properties (density, cp, temperature).

Returns
-------
dict
    Dictionary containing film effectiveness, remaining coolant flow, and
    heat-flux reduction factor.
