In this paper we investigate algorithms based on the Fast Legendre Transform (FLT) in order to compute tabulated Equation Of State (EOS) for fluids with phase transition. The equation of state of a binary mixture is given by an energy minimization principle. According to the miscible or immiscible nature of the mixture, the energy of the system is either a convex envelope or an inf-convolution ...

In Kalina power generation as well as vapor absorption and refrigeration systems ammonia-water mixture has been used as working fluids. Unlike for pure components, binary mixtures additionally need mixture concentration to solve thermodynamic properties. A flowchart is developed to understand the computations of the properties. The thermodynamic properties for ammonia-water mixture have been ge...

abstract: â in this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. for this purpose, the tangent plane distance (tpd) minimization method was used. first, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. the results show that for a binary mixture of th...

The statistical mechanics of directed line-like objects, such as directed polymers in an external field, strands of dipoles in both ferroand electrorheological fluids, and flux lines in high-TC superconductors bears a close resemblance to the quantum mechanics of bosons in 2 + 1 dimensions. We show that single component and binary mixture critical phenomena in these systems are in the universal...

Mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of Mg2Ni and Mg(2-x)MnxNi (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. X-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

The lack of variation in antifungal drugs, and the misuse or inappropriate use usually causes resistant strains of the yeast in human’s normal flora. Unfortunately, a large number of Candida infection cases in immunosuppressed patients with insufficient treatment eventually can cause patient's death. The aim of this study was to evaluate the in vitro conventional antifungal azole compounds with...

A method to compute invariant tori in high-dimensional systems, obtained as discretizations of PDEs, by continuation and Newton-Krylov methods is described. Invariant tori are found as fixed points of a generalized Poincaré map without increasing the dimension of the original system. Due to the dissipative nature of the systems considered, the convergence of the linear solvers is extremely fast...
