Аннотация: The results of the experimental investigations on the heat transfer of thin wires with water/oil and ether/water emulsions are given. The temperature of normal oil boiling is not lower than 340°C. A considerable delay in the crisis of bubble boiling is obtained for both emulsions, and is particularly noticeable for the ether/water emulsion. In the latter case the coefficient of connective heat transfer and the density of heat flux substantially exceed the corresponding values for pure initial liquids in the entire investigated range of temperatures (from 20 to 230°C) and pressures (from 0.1 to 3.6 MPa)

Аннотация: The heat transfer from thin wires to emulsions with a disperse phase formed from a liquid whose boiling temperature is much lower than the boiling temperature of the disperse medium was investigated. Experiments were conducted at atmospheric pressure on vertical and horizontal wires from 50 to 100 ?m in diameter with n-pentane/glycerine, diethyl ether/water, and freon-113/water and water/oil emulsions.??It was possible to describe the experimental data obtained by one analytical dependence Nu = AArPrM?1[1 ? exp(?JVt)]. The dependence presented was obtained from the proposed model of the chain branched activation of boiling centers in droplets of a superheated liquid. In this case the coefficient J acquires the meaning of the activation rate of these centers.??

Заглавие : Characteristic features of the boiling of emulsions having a low-boiling dispersed phase
Место публикации : Journal of Engineering Physics and Thermophysics. - 2006. - Vol. 79, № 6. - С. 1130-1133
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): boiling
Аннотация: The results of investigation of heat transfer from thin wires to a boiling emulsion, the dispersed phase of which is formed from a liquid with a boiling temperature much lower than the boiling temperature of the dispersion medium, are presented. Two variants of boiling of such an emulsion are possible: boiling of the dispersed phase alone and simultaneous boiling of the dispersed phase and dispersion medium. In the present work, only the first variant has been studied; it is distinguished by the following most important features: high superheat of the dispersed-phase droplets ?Tsubsup/sub of the emulsion and a wide temperature range of bubble boiling (50–200°C). For conventional heat carriers (pure liquids and solutions), the value of ?Tsubsup/sub does not exceed 1–10°C, with the bubble-boiling interval lying within the range from 5 to 20°C.

Заглавие : Results of experimental investigation of heat transfer with emulsions with low-boiling disperse phase

ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): heat trahsfer
Аннотация: The results are given of a theoretical investigation of heat transfer from thin wires to emulsions in which the disperse phase is low-boiling compared to the dispersion medium. A special feature of heat transfer to such emulsions is observed in the mode of nucleate boiling, when only the droplets of the disperse phase of emulsion are boiling. The transition from the convective mode of heat transfer to nucleate boiling requires high values of temperature gradient ? T = T sub W /sub ? T sub0/sub at which the temperature of the heat-transfer surface T sub W /sub is higher than the temperature T sub S /sub of saturated vapors of the disperse phase by 100 °C and more. Here, T sub0/sub is the temperature of the heat-transfer agent away from the heat-transfer surface. Note that, for pure liquids and solutions, the value of delay of the beginning of boiling ? T sub i /sub = T sub W /sub ? T sub S /sub as a rule does not exceed 1–5 °C. Another feature of heat transfer to the emulsions being treated is a wide temperature range of the mode of nucleate boiling (over 100 °C); the upper limit of this temperature range is defined by the temperature of transition to film boiling of the dispersion medium of the emulsion being investigated that has already boiled by this instant of time. The value of delay of the beginning of boiling is affected significantly by additions of surfactants and adsorbents.

Заглавие : A method of explosive effervescence of disperse-phase droplets for analysis of emulsions

Ключевые слова (''Своб.индексиров.''): effervescence explosive--disperse-phase droplets--emulsions
Аннотация: A method and an experimental setup for dispersion analysis of emulsions based on overheating and explosive effervescence of disperse-phase droplets are described. Formulas are derived and a procedure for determining the fitting parameters for a description of the dispersive composition of an emulsion is given. The maximum count rate was about 500 droplets per second for droplet diameters ranging from 5 to 200 mu m. The method can be automated to handle high-viscosity, opaque, unstable, and heavily contaminated emulsions

Ключевые слова (''Своб.индексиров.''): heat trahsfer--low temperatures--boiling
Аннотация: The results of an investigation of heat transfer from thin wires to emulsions whose dispersed phase is low-boiling in comparison with its dispersion medium are presented. A peculiarity of heat transfer with such emulsions is observed in the bubble boiling regime when only droplets of the emulsion dispersed phase are boiling. Theoretical and experimental investigations of the activation mechanism of boiling centers have been performed. The critical volume V 0 of the emulsion, with chain nucleation taking place when this volume is exceeded, has been determined. A model of chain activation of low-temperature boiling centers has been developed. The model has been qualitatively confirmed by the experimental data obtained
