摘要:This comment is in response to a comment by Sengers and Anisimov on the article “Gibbs density surface of fluid argon” that contradicts prevailing theory. It has not “been established experimentally that the thermodynamic properties of fluids satisfy scaling laws with u...

摘要:Abstract(#br)This comment is in response to a recent “new comment” by Umirzakov on the article “Gibbs density surface of fluid argon: revised critical parameters.” It was incorrectly asserted that van der Waals equation “proves” the existence of a scaling singulari...

摘要:Abstract(#br)Using argon as the exemplary fluid, we report a representation of equations-of-state in fluid regions bounded by percolation loci with mainly physical constants that define state bounds and characterize the fluid phase diagram. Both gas- and liquid-state pressur...

摘要:Abstract(#br)The thermodynamic state function rigidity, defined simply as \((\mathrm{d}p/\mathrm{d}\rho )_{T}\) , where p is the pressure, \(\rho \) is the density and T is the temperature, is the work required to reversibly increase the density of a fluid. Along any isotherm, ri...

摘要:Abstract(#br)We extend previous investigations into the thermodynamics of liquid state boundaries by focusing on the origins of liquid–gas criticality. The singular point hypothesis of van der Waals is re-examined in the light of recent knowledge of the hard-sphere percolati...

摘要:Abstract(#br)Critical properties for Lennard–Jones fluids are seen to be consistent with an alternative description of liquid–gas criticality to the van der Waals hypothesis. At the critical temperature ( T c ) there is a critical dividing line on the Gibbs density surface r...

摘要:Abstract(#br)We investigate the effect of isochoric cooling of the Lennard–Jones liquid at the triple point i.e. ρ ⁎ = 1.20 r 0 , T ⁎ = 0.70 into the negative pressure region of crystal + vapor phase with temperatures varying from T ⁎ = 1.00 to 0.0001. Along this lin...

摘要:Abstract(#br)We present first-principles calculations using large-scale computer simulations, and a theoretical analysis of the rheology and microstructure of a particulate model undergoing the process of uniaxial compaction. Such a fundamental process underlies many areas o...

摘要:Abstract(#br)A phase diagram of simple fluids, based upon percolation transition loci determined from literature experimental density-pressure isotherms of argon, shows three fluid phases. The liquid phase spans all temperatures from a metastable amorphous ground state to su...

摘要:An amorphous ground state reminiscent of random close packing (RCP) of spheres terminates a liquid phase that spans all temperatures. On the Gibbs density surface, the liquid phase has bounded by a supercritical percolation line, two-phase liquid–gas coexistence line, and be...
