摘要/Abstract

摘要： In the two-parameter corresponding states principle(CSP), the critical compressibility
factors of the fluid under study(called "α" fluid) and the reference fluid(called "o"
fluid) must be identical. This is not generally observed in nature. To overcome this
limitation, a perfect shape factor CSP is proposed in which the compressibility factors of
"a" and "o" fluids are corresponded perfectly by introducing a new pressure shape factor 5.
Using methane as the "o" fluid, the shape factors of many fluids are calculated from PVT
properties at saturation state and the second virial coefficients. Models are also
formulated for the shape factors with the assumption of φ is a function of temperature and
volume while θ and δ are temperature dependent only. The models described the shape
factors satisfactorily in whole region including vapor, liquid and their co-existing
phases. The perfect shape factor CSP could be applied for both polar and non-uolar fluids.
