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: 

$Load Component Library

$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}
