The change in water particle diameters injected into the vapor compression process, the water phase temperature and the vapor phase temperature were measured in the compression process. The experimental conditions were approx. 2 at a compression ratio under 100 kPa in pressure, 340-390 Kin temperature range, 2-8 Hz in rotational speed. The mass ratio of injected water was small: in the order of...

Phase transitions of small isolated systems are signaled by the shape of the caloric equation of state e∗(T ), the relationship between the excitation energy per nucleon e∗ and temperature. In this work we compare the experimentally deduced e∗(T ) to the theoretical predictions. The experimentally accessible temperature was extracted from evaporation spectra from incomplete fusion reactions lea...

CONCURRENT EVAPORATING SPRAY JETS IN DILUTE GAS-SOLIDS PIPE FLOWS by Xiaohua Wang Evaporating spray jets into gas-solids suspensions are encountered in many industrial applications. The rapid evaporation of spray jets has significant effects on the gas-solids mixing near the jet nozzle regions, including non-uniform solids concentration dilution, gas/solids temperature reduction, and gas/solids...

The techniques of waste water treatment have reached nowadays a very advanced stage of development. As a result of the importance that must be attributed to this area, the Commission on Water Quality of IUPAC has decided to give a survey of processes which are used now. Beside the conventional mechanical and biological waste water treatment preferably flocculation, precipitation, adsorption, ev...

We present a theoretical analysis of the evaporative cooling of a magnetically guided atomic beam by means of discrete radio-frequency antennas. First we derive the changes in flux and temperature, as well as in collision rate and phase-space density, for a single evaporation step. Next we show how the occurrence of collisions during the propagation between two successive antennas can be probed...

Here we report the first demonstration for centro-apical self-organization of organic semiconductors in a line-printed organic semiconductor: polymer blend. Key feature of this work is that organic semiconductor molecules were vertically segregated on top of the polymer phase and simultaneously crystallized at the center of the printed line pattern after solvent evaporation without an additive ...

Evaporation of liquids is a fundamental phenomenon pertaining to a wide range of industrial and biological processes. In this paper we present recent results on evaporation of liquids and interfacial phenomena in the case of two configurations: menisci in micro-channels and sessile wetting droplets . Interfacial temperature is a key factor in the phase change process. The access to the interfac...

Aqueous core/polymer shell microcapsules with mononuclear and polynuclear core morphologies have been formed by internal phase separation from water-in-oil emulsions. The water-in-oil emulsions were prepared with the shell polymer dissolved in the aqueous phase by adding a low boiling point cosolvent. Subsequent removal of this cosolvent (by evaporation) leads to phase separation of the polymer...

A spraying evaporation system applied to brine disposal is reported, which is mainly used for disposing the brine with concentration more than 100,000 mg/L. A computational fluid dynamics (CFD) simulation has been carried out to study the brine droplet evaporation and diffusion process in high temperature air flow. A discrete-phase model in spraying evaporation system is developed and a simulat...
