A modified van der Waals equation of state recommended in the literature for improved prediction of the inversion curve of air is shown to be thermodynamically inconsistent, giving large errors in the critical and two-phase regions. An alternative procedure is presented by means of which the cohesio

The integral inversion curve (IIC) is the contour of all thermodynamic states (P,T) which exhibit a zero integral cooling under Joule-Thomson (isenthalpic) expansion from a pressure, P, down to ambient atmospheric pressure. This is an alternative and complementary presentation of the Joule-Thomson i
One of the most important applications of cryogenics is the separation and purification of air into its various components. Furthermore, of the many basic processes by which low temperatures are attained, the most commonly used in practical refrigerators is the Joule-Thomson expansion process. In th
