Desuperheater / attemperator simulation

1 inlet (superheated steam) -> 1 outlet (tempered steam)

Governing equations

The exact equations the solver works for a desuperheater / attemperator — the same math shown in the app's "Theory" panel, not a black box.

mw=mshshouthouthwm_w = m_s\,\frac{h_s - h_{out}}{h_{out} - h_w}
mout=ms+mw,ToutTtarget (Tsat)m_{out} = m_s + m_w,\qquad T_{out}\to T_{target}\ (\ge T_{sat})
m_s
steam inlet flow [mol/s]
m_w
spray-water flow (solved) [mol/s]
m_{out}
tempered-steam outlet flow [mol/s]
h_s
inlet steam enthalpy [J/mol]
h_w
spray-water enthalpy [J/mol]
h_{out}
outlet enthalpy [J/mol]
T_{target}
desired outlet temperature [K]
T_{sat}
saturation temperature [K]

Parameters

outlet_temperature [K, required, >= saturation]; optional spray_temperature [K, default 300] and pressure_drop [Pa]. Solves spray-water flow to hit the target; reports spray_flow. Use SteamPkg/IAPWS thermo
