Solution of the span – wagner equation of state using a density – energy state function for fluid - dynamic simulation of carbon dioxide / Knut Erik Teigen Giljarhus in Industrial & engineering chemistry research, Vol. 51 N° 2 (Janvier 2012)

In this work, we propose a method for dynamic simulations of carbon dioxide using the Span–Wagner reference equation of state. The simulations are based on using the density and internal energy as states, which is a formulation naturally resulting from mass and energy balances. The proposed numerical method uses information about saturation lines to choose between single-phase and two-phase equation systems, and is capable of handling phase transitions. To illustrate the potential of the method, it is applied to simulations of tank depressurization, and to fluid-dynamic simulations of pipe transport.
