Engineering equations of state (EOS) deal with the majority of fluids of interest in process and equipment design in the chemical industries. Accuracy and universality are two desirable features the engineering EOS require, however, both of them cannot be simultaneously obtained without some degree of compromise. Therefore a simultaneous optimization algorithm is proposed to develop an accurate...

We consider the possibility of having hybrid stars with a phase transition from hadrons into strange matter at core neutron star in ? equilibrium. For hadron equation state (EoS) quark-meson coupling model is used, while MIT bag used to describe phase. The treated using Gibbs construction method and results are calculated checked against observational constaints imposed on EoS. also compared ha...

In this paper, we seek to answer the question "given a rotating core collapse gravitational wave signal, can determine its nuclear equation of state?". To question, employ deep convolutional neural networks learn visual and temporal patterns embedded within (GW) signals in order predict state (EOS). Using 1824 GW simulations by Richers et al. (2017), which has 18 different EOS, consider be clas...

We study eigenmodes of acoustic oscillations of high multipolarity l ∼ 100–1000 and high frequency (∼100 kHz), localized in neutron star envelopes. We show that the oscillation problem is self-similar. Once the oscillation spectrum is calculated for a given equation of state (EOS) in the envelope and given stellar mass M and radius R, it can be rescaled to a star with any M and R (but the same ...

Using density-functional theory-based molecular-dynamics simulations, we have investigated the equation of state for silicon in a wide range of plasma density and temperature conditions of ρ=0.001-500g/cm^{3} and T=2000-10^{8}K. With these calculations, we have established a first-principles equation-of-state (FPEOS) table of silicon for high-energy-density (HED) plasma simulations. When compar...

Thermodynamic consistency test of isothermal vapor-liquid equilibrium (VLE) data of various binary systems containing Carbon dioxide (CO2)/Room temperature ionic liquids (RTILs) have been investigated in wide ranges of pressures in each isotherm precisely. In this paper Generic van der Waals (GvdW) equation of state (EoS) coupled with modified van der Waals Berthelot mixing rule has ...

an analytical equation of state by song and mason is developed to calculate the pvt properties ofmercury. the equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. there exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...

Emissions of free neutrons and protons from the central collisions of Sn+Sn and Sn+Sn reactions are simulated using the Improved Quantum Molecular Dynamics model with two different density dependence of the symmetry energy in the nuclear equation of state. The constructed double ratios of the neutron to proton ratios of the two reaction systems are found to be sensitive to the symmetry terms in...
