Properties of the chemical element helium.
Project description
heprops
is a simple python package implementing useful properties of the chemical element helium at low temperature
It includes experimental data and interpolation for the data found in the incredible and useful paper:
- James S. Brooks and Russell J. Donnelly, The calculated thermodynamic properties of superfluid helium-4, J. Phys. Chem. Ref. Data 6 51 (1977).
Most of the data in this paper was available on the late Russel Donnelly's former website http://pages.uoregon.edu/rjd which has since been taken offline but it is still available via a 2015 snapshot on the WayBackMachine.
Supported Python Versions
Python >= 3.6 (for f-strings)
Installation
To install via pip:
pip install heprops
Usage
At present the package has a single module helium
which contains a number of functions that return the thermodynamics properties of helium. For example:
from heprops import helium
import numpy as np
T = np.linspace(0.5,2.5,5)
# the superfluid fraction
ρsoρ = helium.superfluid_fraction_SVP(T)
print(ρsoρ)
# the coherence length
ξ = helium.ξ(T)
print(ξ)

Support
The creation of this software was supported in part by the National Science Foundation under Award Nos. DMR-1808440 and DMR-1809027.
