© 2022 Elsevier B.V.Landau phenomenological model is applied to two binary mixtures (tetradecane + hexadecane and tetradecane + pentadecane) to calculate T−x (temperature - composition) phase diagram under high pressure for their solid – liquid equilibria. The phase line equation derived from the free energy of the solid phase is fitted to the experimental liquidus curve (T−x) from the literature and the parameters in the Landau expansion are determined. As observed experimentally, variation of the temperature with the composition below and above Te (minimum melting temperature) is almost linear at the pressures from 0.1 to 100 MPa in these binary mixtures. Our results indicate that the influence of pressure on liquid – solid equilibria can also be studied for the other binary mixtures or two – components systems by the Landau mean field model, as studied here.

Calculation of the P-T phase diagram of nitrogen using a mean field model
Enginer, Y.; Algul, G.; Yurtseven, Hasan Hamit (2017-12-20)
The P-T phase diagram is calculated at low and moderate pressures by obtaining the phase line equations for the transitions considered in nitrogen using the Landau phenomenological model. For some transitions, a quadratic coupling between the order parameters is taken into account in the expansion of free energies in terms of the order parameters. A quadratic function in T and P is fitted to the experimental P-T data from the literature and the fitted parameters are determined.
Calculation of the T-X phase diagram for a mixture of liquid crystals
Yurtseven, Hasan Hamit; Salihoglu, S (2000-12-01)
In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. There is a very good agreement between our calculated and the experimentally observed phase diagram.
Calculation of the thermodynamic functions using a mean field model for the fluid-solid transition in nitrogen
AKAY, Özge; Yurtseven, Hasan Hamit (Romanian Academy - Revue Roumaine De Chimie, 2020-05-01)
Temperature and pressure dependence of the thermodynamic quantities are calculated using the Landau phenomenological model for the first order fluid-solid transition in nitrogen. This calculation is performed by fitting the phase line equation as derived from the mean field model to the observed T-P phase diagram of the fluid-solid transition in N2 from the literature. Our calculations show that the order parameter and the inverse susceptibility decrease whereas the entropy, heat capacity, thermal expansion...
Calculation of the phase diagram of n-alkanes (CnH2n+2) by the Landau mean field theory
Yurtseven, Hasan Hamit; Kilit Dogan, E. (2022-05-01)
We study the temperature T and concentration n (number of carbon atoms) dependence on the transitions of the liquid, rotator (RI, RII,RIII,RIVand RV) and crystal phases in n-alkanes (CnH2n+2). The Landau phenomenological model is used by expanding the free energy in terms of the lattice distortion parameter (D) and the tilt angle (θ) of the rotator (and crystal) phases with their quadratic coupling (D2θ2).The phase line equations are obtained with some approximations by considering the first order transitio...
Calculation of the Dielectric Constant of a Ferroelectric Liquid Crystal From a Mean Field Model
YURTSEVEN, HASAN HAMİT; Yurtseven, Hasan Hamit (2011-01-01)
The static dielectric constant epsilon(perpendicular to) of the ferroelectric liquid crystal 4-(3-methyl-2-chlorobutanoyloxy)-4'--heptyloxybiphenyl (A7) with high spontaneous polarization is calculated as a function of temperature using a mean field model. This calculation is performed close to the smectic A-isotropic liquid (SmA-I) transition for pure optically active compound (T-c = 81.6 degrees C). For this calculation of epsilon(perpendicular to), the free energy of the SmA phase is expanded in terms of...
