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) |

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 ?Tsup 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 ?Tsup does not exceed 1–10°C, with the bubble-boiling interval lying within the range from 5 to 20°C. \\\\Expert2\\NBO\\Journal of Engineering Physics and Thermophysics\\2006, v.79, N 6, P.1130.pdf |

Turchaninova // High Temperature. - 2006. - Vol. 44, № 2. - С. 267-282 Рубрики: ФИЗИКА Кл.слова (ненормированные): 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 W ? T 0 at which the temperature of the heat-transfer surface T W is higher than the temperature T S of saturated vapors of the disperse phase by 100 °C and more. Here, T 0 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 i = T W ? T S 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. \\\\Expert2\\NBO\\High Temperature\\2006, v.44, p.267.pdf |

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 |
