Description:

The function determines various thermodynamic properties of Sodium based on Argonne National Lab (ANL) data and correlations. Different possibilities exist for the combinations between the input/output properties:

- h-->T {'H2T','h2T'}. for Temperature [°C] as a function of Enthalpy [kJ/kg].

- T-->h {'T2H','T2h'}. for Enthalpy [kJ/kg] as a function of Temperature [°C].

- T-->rho {'T2rho'}. for Density [kg/m3] as a function of Temperature [°C].

- T-->Cp {'T2Cp','T2cp'}. for Specific Heat [kJ/kg.K] as a function of Temperature [°C].

- T-->mu {'T2mu'}. for Dynamic Viscosity [Pa.s] as a function of Temperature [°C].

The function is thought to be applied to Liquid Sodium, therefore its temperature validity field is 98°C-881°C. Despite XSodium can handle values outside range without resulting in an error, it does not mean that they are precise or, more in general, possible.

Procedure:

The user shall input the desired function mode and related input. The function will assess that the validity field is respected, and eventually force the input to fit within, then determine the output.

---------------------------------------------------------------------------------------------------------------------

Inputs:

The function accepts a thermodynamic property according to the following list:

- Temperature [°C] Range: 98-881 [°C] / 371-1154 [K]

- Entalphy [kJ/kg] Range: 207-1214 [kJ/kg]

---------------------------------------------------------------------------------------------------------------------

Outputs:

- Temperature [°C] T

- Enthalpy [kJ/kg] h

- Specific heat (isobaric) [kJ/kg.K] Cp

- Density [kg/m3] rho

- Dynamic Viscosity [Pa.s] mu
