Nozzle1_CL
Adiabatic nozzle model with a specified efficiency.
Inputs:
h_in: inlet enthalpy (J/kg, kJ/kg, or Btu/lbm)
P_in: inlet pressure (bar, atm, Pa, kPa, MPa)
Vel_in: inlet velocity (m/s, ft/s)
P_out: outlet pressure (bar, atm, Pa, kPa, MPa)
F$: fluid string identifier
eta: efficiency of nozzle
Outputs:
h_out: outlet enthalpy (J/kg, kJ/kg, or Btu/lbm)
Vel_out: outlet velocity (m/s, ft/s)
Ma_out: outlet Mach number
Example:
$UnitSystem SI Mass J K Pa
F$='CarbonDioxide'
T_in=500 [K]
P_in=4e5 [Pa]
h_in=Enthalpy(F$,T=T_in,P=P_in)
Vel_in=0 [m/s]
P_out=2.3e5 [Pa]
eta=0.9
Call Nozzle1_CL(h_in, P_in, Vel_in, P_out, F$, eta: h_out, Vel_out, Ma_out)
{Solution:
h_out = 142971 [J/kg]
Vel_out = 298.5 [m/s]
Ma_out = 0.9159}
