Measurements of the spontaneous polarization in KH(2)PO(2)
… direct determinations of (OP/OT)e, demonstrating thermodynamic consistency of the measurements. The transition is first order with a discontinuous jump in the polarization of 1.87 uc/cm(2) at the transition. Laudau theory allows separate calculation at specific heat contributions of the lattice …

Thermodynamically consistent modelling and computational methods for multiphase flows
… methods. The key point for this work is the thermodynamic con- sistency. We begin by introducing an extension of the Model H to study the two-phase flows with thermocapilliary effects, where we assume that the coefficient of the surface tension is temperature dependent, and the classical …

Estimation method for the thermochemical properties of polycyclic aromatic molecules
… formation of PAH and other aromatic molecules. Thermodynamic consistency requires that reverse rate constants be calculated from the forward rate constants and from the equilibrium constants. The later are obtained from the thermochemical properties of reactants and products. The predictive …

The Automated Construction and Verification of Physically Plausible Models of Physiological Systems
… on models violating fundamental physical and thermodynamic principles, no systematic approach exists for assessing model credibility and reliability in systems biology. Consequently, modellers in this field have introduced various methods to assess model outputs by comparing simulation results …

Application of Semi-Grand Canonical Monte Carlo (SGMC) methods to describe non-equilibrium polymer systems
… of experimental measurements. I assert that thermodynamic consistency and energy minimization is an integral part of this endeavor; reliable analyses of structure and properties are built upon the foundation of a minimum-free-energy ensemble of configurations that reproduces the experimental …

Vapour-liquid equilibrium studies at atmospheric to moderate pressures
… at one atmosphere pressure. A Barker-type consistency test computer program, which allows for association in both phases has been applied to the data generated and clearly shows that the stills produce data of a very high quality. Two high quality data sets, for the mixture …

Batch separation of tetrafluoroethylene, hexafluoropropylene and octafluorocyclobutane
… experimental data and the model also passed the thermodynamic consistency test for all the systems and isotherms. The design simulations were completed by means of the Aspen Batch Distillation, a module of the Aspen Technologies package. The results show that the optimum design for recovering …

Structure and interactions of colloidal particles at fluid interfaces
… parameter which is determined by requiring thermodynamic consistency between the virial and compressibility equations of state. The accuracy of these schemes are tested against Monte Carlo simulation data from monolayers interacting via a wide range of commonly encountered pair potentials. …

Experimental study and modeling analysis of ion transport membranes for methane partial oxidation and oxyfuel combustion
… surface reaction mechanism that preserves thermodynamic consistency and conserves site balance and electroneutrality. Charged species diffusion is modeled using the dilute-limit Poisson-Nernst-Planck formulation that accounts for transport due to concentration gradient as well as …

Stable algorithms for generalized thermoelasticity based on operator-splitting and time-discontinuous Galerkin finite element methods
… part of this work concerns the formulation of a thermodynamically consistent generalized model of nonlinear thermoelasticity, whose linearization about a natural reference configuration includes the theory of Green and Naghdi. The generalized model is based on the fundamental laws of continuum …

Exotic Stars and Thorne-Żytkow Objects
… in these earlier models. I have investigated the thermodynamic consistency of these models and how robust the qualitative structure of the solutions is to changing accretion rates and other boundary conditions. I found that our use of revised, updated tables of thermal neutrino loss rates compared …
