“…19,72,96,98,101,[103][104][105] It must be underlined that Eq. (125) is consistent with the cybotactic theory 38 and the significant structure theory 113 adapted to feature a picture of electrolyte-water systems comprising submicroscopic parts such as pure electrolyte, electrolyte with small amounts of water, ordinary water, perturbed water, ion pairs, complex ion clusters …whose relative quantities vary with the water mole fraction. The fact that Eq.…”

“…Eyring attempted to relate this change in fluidity to “holes” in the fluid that increase in size as the fluid expands. Whereas his results were more theoretically based, they are difficult to generalize and are known to be incorrect from an actual fluid structure point of view . Corresponding states methods provide an empirical relationship between fluid expansion and viscosity but use shape factors to develop a correspondence between a reference fluid and the desired fluid .…”

The viscosity of pure hydrocarbons was correlated using a simple function based on the fluid density. The correlation has three adjustable parameters, a compressed state density, F s °, an empirical parameter, c 2 , that scales the viscosity response to fluid expansion, and another empirical parameter, c 3 , used to tune at pressures above 10 MPa. The inputs to the correlation are the fluid density, pressure, and low-pressure gas viscosity. The correlation fit experimental viscosities for 39 pure hydrocarbons including n-alkanes, branched alkanes, alkenes, cyclics, and aromatics, within experimental error over a broad range of temperatures and pressures. Heavy hydrocarbons such as mineral oils were also fit with an AAPRD of 2.7%. Binary mixture viscosities were predicted to within 10% using simple volumetric mixing rules. The method provides a single framework for liquid and vapor phases, is simple to implement, and is very fast computationally, making it ideal for incorporation into process and reservoir simulators.

“…Another option used is based on using significant liquid structure (SLS) theory for the liquid phase. The SLS theory , is based the following considerations and experimental facts: (a) For a normal phase transition from solid to liquid, there is always an expansion in volume, water (and a few other compounds) being considered an exception. (b) At the triple point the vapor pressures of both solid and liquid states are the same.…”

Melting Is Well-Known, but Is It Also Well-Understood?

Contrary to continuous phase transitions, where renormalization group theory provides a general framework, for discontinuous phase transitions such a framework seems to be absent. Although the thermodynamics of the latter type of transitions is wellknown and requires input from two phases, for melting a variety of one-phase theories and models based on solids has been proposed, as a generally accepted theory for liquids is (yet) missing. Each theory or model deals with a specific mechanism using typically one of the various defects (vacancies, interstitials, dislocations, interstitialcies) present in solids. Furthermore, recognizing that surfaces are often present, one distinguishes between mechanical or bulk melting and thermodynamic or surface-mediated melting. After providing the necessary preliminaries, we discuss both types of melting in relation to the various defects. Thereafter we deal with the effect of pressure on the melting process, followed by a discussion along the line of type of materials. Subsequently, some other aspects and approaches are dealt with. An attempt to put melting in perspective concludes this review.
