Inversion de l'effet de Joule-Thomson dans les gaz à faible facteur acentrique

Written by sctunisie no comments

Inversion data for the low acentric factor gases (N2, O2, Air, CH4, Ne, Ar) are correlated with a simple model Pr = 32.771 - 60.859e-Tr - 6.535Tr in terms of the reduced temperature and pressure Tr and Pr. The so obtained differential inversion curve has a peak located at (Tr = 2.23, Pr = 11.66) and its maximum reduced inversion temperature at zero pressure is 4.95. The fitting technique used is based on the structural optimization method developed by Wagner.
