Influence of microscopic inhomogeneity in binary liquid mixtures on their vibrational spectra is studied by doing calculations on a model liquid system. The concentration dependence of the noncoincidence effect (NCE), which is a feature of vibrational bands related to the intermolecular resonant coupling of vibrational modes, is analyzed. It is suggested that observation of convex behavior of t...

Using Monte Carlo simulation and mean-field calculations, we study the liquid-vapor phase diagram of a square-well binary fluid mixture as a function of a parameter d measuring the relative strength of interactions between particles of dissimilar and similar species. The results reveal a rich variety of liquid-vapor coexistence behaviors as d is tuned. Specifically, we uncover critical end poin...

Liquid marble is a liquid droplet coated with particles. Recently, the evaporation process of a sessile liquid marble using geometric measurements has attracted great attention from the research community. However, the lack of gravimetric measurement limits further insights into the physical changes of a liquid marble during the evaporation process. Moreover, the evaporation process of a marble...

At present, the method adapted to analyze the phase equilibrium properties of refrigerant mixtures is as follows: Firstly, based on some experimental data of· phase equilibrium, the interactire factor bet~een the mixed refrigerants can be derived by using a equation of stalL Second!~ the rapour and liquid phase equilibrium properties are predicted by combining the mixed rule with phase equilibr...

Abstract: We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture of CO2 and H2 in the presence of microscopic floating solid catalytic particles. We describe the sys...

nucleate pool boiling heat transfer coefficient have been experimentally measured on a horizontal rod heater for various liquid binary mixtures. measurements are based on more than three hundred data points on a wide range of concentrations and heat fluxes. in this investigation, it has been confirmed that the heat transfer coefficient in boiling solutions are regularly less than those in pure ...

In this paper we calculate the interfacial resistances to heat and mass transfer through a liquid-vapor interface in a binary mixture. We use two methods, the direct calculation from the actual nonequilibrium solution and integral relations, derived earlier. We verify, that integral relations, being a relatively faster and cheaper method, indeed gives the same results as the direct processing o...

The ultrasonic velocity (u), density (ρ) and viscosity (η) related thermo-acoustic parameters are the important tools in understanding nature extent of pattern molecular interactions between components liquid mixture. velocity, viscosities binary mixture containing Acetonitrile 2- Propanol over whole concentration range have been measured at 305.15K. This data used to compute derived like adiab...
