An Improved ISM Equation of State for Polar Fluids
We developed an equation of state (EOS) by Ihm, Song, and Mason (ISM) for polar fluids. The model consists of four parameters, namely, the second virial coefficient, an effective van der Waals co-volume, a scaling factor, and the reduced dipole moment. The second virial coefficient is calculated from a correlation that uses the heat of vaporization, and the liquid density at the normal boiling ...
متن کاملEquations of state for fluids: The Dieterici approach revisited
In 1873, van der Waals proposed a simple equation of state that qualitatively described the phase behavior of fluids. Since then, the principles behind the van der Waals equation have been used and refined countless times in the quest for an accurate equation of state. Despite the enormous amount of work reported, the goal of a simple and accurate equation of state for even relatively simple sy...
متن کاملStatic perfect fluids with Pant-Sah equations of state
We analyze the 3-paramter family of exact, regular, static, spherically symmetric perfect fluid solutions of Einstein’s equations (corresponding to a 2-parameter family of equations of state) due to Pant and Sah and ”rediscovered” by Rosquist and by the present author. Except for the Buchdahl solutions which are contained as a limiting case, the fluids have finite radius and are physically real...
متن کاملFast Evaluation of Complex Equations of State
One of the most common operations encountered in computational fluid dynamics (CFD) solvers is the evaluation of the caloric and thermal equations of state (EoS) which are required to compute thermodynamic state variables from the conserved values that are typically being advanced by the simulation. The complexity of these calculations can vary widely depending on the nature of the fluid under ...
متن کاملApplication of Carnahan-Starling-vdW-β Equation of State for Refrigerant Fluids
Herein, the application of Carnahan-Starling-vdW-β equation of state (EoS) for 13 refrigerant fluids was investigated. The EoS could predict the saturated liquid densities of these refrigerants over the temperature range of 100-400 K and pressures from zero up to187 MPa with the average absolute deviations of 2.66%. The accuracy of Carnahan-Starling-vdW-β EoS in liquid density prediction was al...
