Turbine simulation

1 inlet -> 1 outlet (expands vapor, extracts shaft work)

Governing equations

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

S(T2s,P2)=S(T1,P1)(real-gas isentropic, solved for T2s)S(T_{2s}, P_2) = S(T_1, P_1) \quad(\text{real-gas isentropic, solved for } T_{2s})
T2=T1+η(T2sT1),Wshaft=F(H(T1,P1)H(T2,P2))T_2 = T_1 + \eta\,(T_{2s}-T_1),\qquad W_{shaft} = F\,(H(T_1,P_1) - H(T_2,P_2))
T
temperature [K]
P
pressure [Pa]
S
molar entropy [J/mol/K]
H
molar enthalpy [J/mol]
\eta
isentropic efficiency
W_{shaft}
shaft power extracted [W]
F
molar flow [mol/s]

Parameters

outlet_pressure [Pa, < inlet]; efficiency [default 0.80] — isentropic expansion, extracts shaft power (reported as power [W]); steam-tables package for Rankine/geothermal binary-cycle work
