The Mathematical Theory of Finite Element Methods
TL;DR: In this article, the construction of a finite element of space in Sobolev spaces has been studied in the context of operator-interpolation theory in n-dimensional variational problems.

Equilibrium constants from a modified Redlich-Kwong equation of state
TL;DR: In this article, a modified Redlich-Kwong equation of state is proposed, which can be extended successfully to multicomponent-VLE calculations for mixtures of nonpolar substances, with the exclusion of carbon dioxide.

A New Equation of State for Carbon Dioxide Covering the Fluid Region from the Triple‐Point Temperature to 1100 K at Pressures up to 800 MPa
Roland Span,Wolfgang Wagner +1 more
TL;DR: In this article, the authors present a new equation of state in the form of a fundamental equation explicit in the Helmholtz free energy, which is able to represent even the most accurate data to within their experimental uncertainty.
