A modified Trebble—Bishnoi equation of state: thermodynamic consistency revisited

摘要: Abstract An inconsistency in thermodynamic property prediction using the Trebble—Bishnoi equation of state (TB EOS) was recently identified by scientists at Shell research center Amsterdam. Specifically, it found that TB EOS predicted negative values isochoric heat capacity and imaginary for speed sound extremely low temperatures. Subsequent investigation authors has led to conclusion any temperature dependence whatsoever co-volume term van der Waals type equations will result anomalies properties pure fluids extreme conditions. This work presents a discussion implications parameters describes modification which is completely removed from term. By altering attractive parameter we are able correlate phase behavior with modified more accurately than original equation, been corrected.
