Dynamic Viscosity of Binary Fluid Mixtures: A Review Focusing on Asymmetric Mixtures
نویسندگان
چکیده
Abstract A literature review on experimental data for binary mixtures of methane and carbon dioxide with hydrocarbons up to n -hexadecane is presented. Based these data, the extended corresponding states method, two entropy scaling approaches, friction theory are analyzed respect their capability calculating viscosity values increasing asymmetry mixture. It shown that not only model but also underlying thermodynamic equation state has a significant influence result such calculations. Shortcomings identified both in modeling approaches.

On the theory of phase transitions in binary fluid mixtures
The microscopic approach to the description of the phase behaviour and critical phenomena in binary fluid mixtures is proposed. It is based on the method of collective variables with a reference system. The physical nature of the order parameter in a binary mixture is discussed. The basic density measure (GinsburgLandau-Wilson Hamiltonian) is obtained in the collective variable phase space whic...
متن کاملViscosity minima in binary mixtures of ionic liquids + molecular solvents.
The viscosity (η) of four binary mixtures (ionic liquids plus molecular solvents, ILs+MSs) was measured in the 283.15 < T/K < 363.15 temperature range. Different IL/MS combinations were selected in such a way that the corresponding η(T) functions exhibit crossover temperatures at which both pure components present identical viscosity values. Consequently, most of the obtained mixture isotherms,...
متن کاملOn Multicomponent Fluid Mixtures
We consider the flow of the mixture of viscous, heat-conducting, compressible fluids consisting of n different components, each of which has its own density, pressure, and molecular weight but all components having the same velocity and temperature. The mathematical model presented here relies on fundamental principles of continuum mechanics and combustion, where the balance laws, the constitut...
متن کاملFluid-solid transitions on walls in binary hard-sphere mixtures
– We present measurements and theory of a fluid-solid phase transition at a hard, flat wall in a two-sized hard-sphere mixture. With particle concentrations well below the level for bulk phase separation, a fluid monolayer (enriched in the larger spheres) forms at the wall. At slightly higher concentrations, the wall-fluid freezes into a wall-solid phase which coexists with the bulk fluid. Meas...
متن کاملA Lattice Boltzmann Model of Binary Fluid Mixtures
We introduce a lattice Boltzmann model for simulating an immiscible binary fluid mixture. Our collision rules are derived from a macroscopic thermodynamic description of the fluid in a way motivated by the Cahn-Hilliard approach to non-equilibrium dynamics and ensure that a thermodynamically consistent state is reached in equilibrium. The non-equilibrium dynamics is investigated numerically and...
