Reformer Component Class
This class models a fuel reformer that converts Jet-A fuel into hydrogen-rich reformate gas.
It inherits from the base Converter class and implements reformer-specific attributes and methods.
Attributes
----------
tag : str

x_H : float
Mass fraction of hydrogen content in Jet-A [-]
x_C : float
Mass fraction of carbon content in Jet-A [-]
y_H2 : float
Mole fraction of hydrogen content in reformate [mol]
y_CO : float
Mole fraction of carbon monoxide content in reformate [mol]
rho_F : float
Density of Jet-A [g/cm^3]
rho_S : float
Density of water [g/cm^3]
rho_A : float
Density of air [g/cm^3]
MW_F : float
Average molecular weight of Jet-A [g/g-mol]
MW_S : float
Average molecular weight of steam [g/g-mol]
MW_C : float
Average molecular weight of carbon [g/g-mol]
MW_H2 : float
Average molecular weight of hydrogen [g/g-mol]
A_F_st_Jet_A : float
Stoichiometric air-to-fuel mass ratio [lb_Air/lb_Jet_A]
theta : float
Contact time [sec^-1]
LHV_F : float
Lower heating value of Jet-A [kJ/g-mol]
LHV_H2 : float
Lower heating value of Hydrogen [kJ/g-mol]
LHV_CO : float
Lower heating value of Carbon Monoxide [kJ/g-mol]
V_cat : float
Catalyst bed volume [cm^3]
eta : float
Reformer efficiency [-]
Notes
-----
The reformer model includes parameters for:
* Fuel composition and properties
* Reformate composition
* Reformer geometry and performance characteristics
* Thermodynamic properties of reactants/products
