Description

The component is used to set the thermodynamic data for all species as well as nominal values for the domain variables.

Ports

Conserving

  • Gas conserving port

    Port_B = Gas;  
    

Parameters

Options

  • Option to select the thermodynamic model (Equation of State)

    model = ThermodynamicModel.IdealGas;     % Thermodynamic Model
    

    Ideal Gas | Real Gas (Peng-Robinson EoS)

Thermodynamic Data

  • Number of Species

    N  = {2,'1'};   
    
  • Species Identifier

    Ids = {[1;2],'1'};
    
  • Molar Weights

    Mw = {zeros(N,1),'g/mol'};                
    
  • Diffusion Volumes after Fuller et al.(Robert C. Reid and John M. Prausnitz and Thomas K. Sherwood, 1977).

    Dv = {zeros(N,1),'1'};
    
  • Temperature Table

    table_T = {[200,400],'K'}; 
    

    with nT als the number of entries of array table_T. For details see Domain.

  • Specific Heats Table

    table_cp = {zeros(nT,N),'J/(mol*K)'};      
    
  • Enthalpy Table

    table_H  = {zeros(nT,N),'kJ/mol'};        
    
  • Gibbs Energy Table

    table_G  = {zeros(nT,N),'kJ/mol'};    
    
  • Dynamic Viscosity Table

    table_mu = {zeros(nT,N),'Pa*s'};          
    
  • Heat Conductivity Table

    table_lambda  = {zeros(nT,N),'W/(m*K)'};  
    
  • Critical Pressures

    pc = {ones(2,1),'bar'}; 
    

    The data are only required if model is set to Real Gas (Peng-Robinson EoS).

  • Critical Temperatures

    Tc = {298.15*ones(2,1),'K'};          
    

    The data are only required if model is set to Real Gas (Peng-Robinson EoS).

  • Acentric Factors

    omega = {ones(2,1),'1'};
    

    The data are only required if model is set to Real Gas (Peng-Robinson EoS).

  • Binary Interaction Coefficients

    k0 = {zeros(2,2),'1'};       
    

    The data are only required if model is set to Real Gas (Peng-Robinson EoS).

Nominal Values

  • Nominal Value for Molar Flow Rates

    F_nom = {1.0e-06,'mol/s'};
    
  • Nominal Value for Energy Flow Rate

    Phi_nom = {1.0,'W'};
    
  • Nominal Value for Molar Enthalpies

    H_nom = {1.0e+02,'kJ/mol'};
    
  • Nominal Value for Departure Enthalpy

    Hres_nom = {1,'kJ/mol'};
