j-jith / pythermophy

Python module for predicting density, heat capacities and speed of sound of pure fluids using Peng-Robinson, (Soave-)Redlich-Kwong and Lee-Kesler equations of state.

pythermophy is a python module for predicting various thermophysical properties of real fluids. The fluids can be currently modelled using the following equations of state:

• Ideal Gas (IG)
• Redlich-Kwong (RK)
• Soave-Redlich-Kwong (SRK)
• Peng-Robinson (PR)
• Lee-Kesler (LK)

At the moment, the following thermophysical properties can be predicted as a function of temperature T (K) and pressure p (Pa):

• Density (kg/m^3)
• Compressibility factor
• Speed of sound (m/s)
• Isobaric specific heat capacity (real and ideal) (J/mol/K)
• Isochoric specific heat capacity (real and ideal) (J/mol/K)
• Departure function of specific heat capacities (J/mol/K)
• Adiabatic index
• Isothermal compressibility (1/Pa)

Installation

To install pythermophy, it is recommended to clone the git repository and use the provided setup.py as follows.

$ git clone https://github.com/j-jith/pythermophy
$ cd pythermophy
$ python setup.py install

The module was written and tested on Python 3, and therefore it is recommended to use pythermophy with Python 3.
