The ammonia-water film condensation is used as an efficient working fluid in industrial applications such refrigeration, plate condenser and evaporator, absorber/generator heat exchange, air-conditioning, pumps separation processes. present work focuses on a numerical investigation of water-ammonia falling binary liquid inside parallel by mixed convection. composed two vertical plates. One the ...

We study the temperature dependence of the heat capacity Cp for the pure CH4 and the coadsorbed CH4/CCl4 on graphite near the melting point. The heat capacity peaks are analyzed using the experimental data from the literature by means of the power-law formula. The critical exponents for the heat capacity are deduced below and above the melting point for CH4 (T = m 104.8 K) and CH4/CCl4 (T = m 9...

If a fluctuating medium is confined, the ensuing perturbation of its fluctuation spectrum generates Casimir-like effective forces acting on its confining surfaces. Near a continuous phase transition of such a medium the corresponding order parameter fluctuations occur on all length scales and therefore close to the critical point this effect acquires a universal character, i.e., to a large exte...

The influence of the unlike Lennard-Jones (LJ) parameters on vapor-liquid equilibria of mixtures is investigated and the performance of eleven combining rules is assessed. In the first part of the work, the influence of the unlike LJ size and energy parameter on vapor pressure, bubble density and dew point composition is systematically studied for the mixtures CO+C2H6 and N2+C3H6, respectively....

The extraction behaviour of zirconium(IV) from sulfuric acid medium has been studied with a binary mixture tri-n-octyl amine (TOA) and Cyanex923 (a four trialkyl phosphine oxides) in kerosene using novel liquid-liquid method. Quantitative TOA was by changing different parameters such as variation, extractant effect chloride ion concentration, temperature, metal concentration diluent effect, pH ...

Recently Escobedo and Mansoori (AIChE J. 42(5): 1425, 1996) proposed a new expression, originally derived from statistical mechanics, for the surface tension prediction of pure fluids. In this report, the same theory is extended to the case of mixtures of organic liquids with the following expression, σm = [(1-Tr,m) Tr,m exp (0.30066/Tr,m + 0.86442 Tr,m) (P 0,m ρL,m P 0,m ρv,m)] 4 P0,m = { ΣiΣj...

Using computer simulations, we establish that the structure of a supercooled binary atomic liquid mixture consists common neighbour structures similar to those found in equilibrium crystal phase, Laves structure. Despite large accumulation crystal-like structure, represents true metastable and can borrow without being destabilized. We consider whether this feature might be origin all instances ...
