saturation_properties(Eos, **sys_dict)[source]

Computes the saturated pressure, liquid, and gas density a one component phase at a temperature.

Input and system information are assessed first. An output file is generated with T, \(P^{sat}\), \(\rho^{sat}_{l}\), and \(\rho^{sat}_{v}\).

Parameters:

  • Eos (obj) – An instance of the defined EOS class to be used in thermodynamic computations.

  • Tlist (list, Optional, default=298.15) – [K] Temperature of the system corresponding Plist. If one value is given, this temperature will be used for all temperatures.

  • MultiprocessingObject (obj, Optional) – Multiprocessing object, MultiprocessingJob

  • kwargs (Optional) – Keyword arguments for calc_saturation_properties()

Returns:

output_dict – Output dictionary containing given and calculated values

  • T: [K] Temperature array generated from given instructions

  • Psat: [Pa] Saturation pressure

  • rhol: [mol/\(m^3\)] Liquid saturation density

  • rholv: [mol/\(m^3\)] Vapor saturation density

Return type:
