Equation of State of Dense Hydrogen in Limiting Cases
نویسنده
چکیده
At higher densities between 0.3 and 0.6 g/cm hydrogen undergoes a transition from a neutral uid to a plasma. Shock wave experiments probe this region along Hugoniot curves. New Z-pinch data [1] are in contradiction to laser induced shock-wave data [2] above 50 GPa. Theoretical descriptions of hydrogen show coincidence with either set of data. Fluid Variational Theory (FVT) describes the neutral uid domain well and yields good agreement with the Hugoniot curve up to about 50 GPa [3]. Using Pad e formulas [4] for the plasma region, we found also a good agreement with the Nova laser shock data [2] above 110 GPa.

Extension of the Dense System Equation of State to Electrolyte Solutions
In this work we have applied the Dense System Equation of State (DSEOS) to electrolyte solutions. We have found that this equation of state can predict the density of electrolyte solutions very accurately. It has been tested for different electrolytes solutions at different temperatures and compositions. A hypothetical binary model has been applied to find the dependencies of parameters of ...

Some new equations of state which are derived for dense fluids in recent years, namely the linear isotherm regularity (LIR), the dense system equation of state (DSEOS), Inm-Song-Mason equation of state (ISM), and a newly derived semi-emperical equation of state have been used to investigate the common intersection point of isobaric expansivity in αp dense fluids. We have shown that the accura...

In the present work, we have examined the ability of some different equations of state in predicting the Joule-Thomson coefficient, ?J-T, of different fluids. For dense fluids, for which density is greater than the Boyle density, ?B, two appropriate equations of state, namely the linear isotherm regularity, LIR, and the dense system equation of state, DSEOS, have been examined. The results show...
متن کاملEXTENSION OF LINEAR ISOTHERM REGULARITY TO LOWER DENSITY RANGE
The general equation of state which was found for dense fluids, both compressed liquids and dense supercritical fluids, namely "Linear Isotherm Regularity," is extended to the lower density range, specifically for densities lower than the Boyle density. This new equation of state which is called "ELIR" is shown to be compatible with the equations of state based on statistical-mechanical the...

Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
