Повний текст джерелаA presente pesquisa trata-se de um estudo teórico e experimental sobre a ebulição convectiva no interior de tubos com fitas retorcidas. A crescente demanda por sistemas térmicos mais compactos e eficientes, nos quais os trocadores de calor apresentam elevada relevância, tem motivado o desenvolvimento de inúmeras técnicas de intensificação de troca de calor, sendo que a utilização de fitas retorcidas é uma das técnicas mais adotadas. Fitas retorcidas são utilizadas como técnicas de intensificação de troca de calor há mais de um século. Entretanto o incremento da transferência de calor é acompanhado do aumento da perda de pressão, que por sua vez implica em aumento da potência de bombeamento, e consequentemente afeta a eficiência global do sistema. Adicionalmente, até os dias de hoje não há consenso sobre as condições operacionais em que o ganho com o incremento do coeficiente de transferência de calor é superior à perda devido ao aumento da perda de pressão. Neste estudo, inicialmente foi realizada uma extensa revisão da literatura sobre a ebulição convectiva no interior de tubos com e sem fitas retorcidas. Esta revisão aborda aspectos relacionados à perda de pressão e ao coeficiente de transferência de calor, juntamente com os métodos de previsão destes parâmetros. Foram realizados experimentos para determinação experimental de perda de pressão e coeficiente de transferência de calor, em aparato experimental contando com tubos horizontais com diâmetros internos iguais a 12,7 e 15,9 mm, para escoamento bifásico de R134a, razões de retorcimento iguais a 3, 4, 9, 14 e tubo sem fita, velocidades mássicas entre 75 e 200 kg/m²s, temperaturas de saturação iguais a 5 e 15°C, e fluxo de calor iguais a 5 e 10 kW/m². Os resultados experimentais foram analisados e comparados com estimativas segundo métodos disponíveis na literatura. Uma análise do aumento do coeficiente de transferência de calor e da perda de pressão friccional é apresentada. Foram verificados incrementos do coeficiente de transferência de calor de até 45% para a mesma potência de bombeamento, e aumento de perda de pressão de aproximadamente 35% para tubos com fitas retorcidas em relação aos tubos sem fita. Adicionalmente, através da comparação dos resultados experimentais com os métodos de previsão para coeficiente de transferência de calor, foi verificado que nenhuma metodologia apresentava previsões satisfatórias dos resultados. Portanto um novo método para previsão do coeficiente de transferência de calor durante ebulição convectiva no interior de tubos com fitas retorcidas foi desenvolvido com base nos resultados experimentais obtidos durante o presente estudo. O método proposto é função de parâmetros geométricos e do escoamento, e também de parâmetros físicos do escoamento rotacional induzido pela fita. A metodologia desenvolvida apresenta previsões satisfatórias dos resultados experimentais, prevendo 89,1% dos resultados experimentais com erro inferior a ± 30% e erro médio absoluto igual a 15,7%.

Повний текст джерелаPresent research deals with an experimental study of the heat transfer and pressure drop of pure and mixtures of refrigerants undergoing convective boiling inside horizontal smooth and microfin tubes. An experimental apparatus has been developed and constructed whose main component is a horizontal tube electrically heated. Experimental results have been grouped into two mass velocity ranges: the one corresponding to mass velocities lower than 200 kg/s.m2, where the stratified flow pattern is dominant, and that for mass velocities higher than 200 kg/s.m2, where typically the annular flow pattern can be found. Effects over the heat transfer coefficient of physical parameters such as mass velocity, heat flux, diameter, saturation temperature, and refrigerant have been investigated and analyzed. It has been found out that the thermo-hydraulic performance of microfin tubes is better than that of the smooth ones. Empirical correlations have been proposed for both the two-phase flow multiplier and the heat transfer coefficient for different ranges of operating conditions as well as for smooth and microfin tubes. Results from the proposed correlations can be deemed adequate for practical applications given the limited dispersion obtained with respect to their experimental counterpart. Noteworthy are the results obtained from correlations for both the two phase flow multiplier for microfin tubes and the heat transfer coefficient for the lower range of mass velocities in smooth tubes. Finally, worth mentioning is the photographic essay developed in present research involving the flow patterns that occur under convective boiling of refrigerants in horizontal tubes.

The microchannel evaporator,which possesses the advantage of high heat transfer coefficient,good temperature uniformity,and small requirement for coolant flow rates,is considered as a potential cooling technology.The porous structure with a large number of nucleation site density as well as the reentrant grooves is to enhance the heat transfer performance in the microchannels evaporator. In present study,the flow boiling experiments were conducted with a plane and porous microchannels evaporator on one square inch copper substrates. Using water as working fluid,the mass flux from103~207 kg/m^2 s and the saturated pressure of 140kpa. Both microchannels have 62 channels(225μm in width;and 660μm in depth).The effects of powder size,thickness of structure upon heat transfer performance are investigated.The comparsions of heat transfer characteristics,pressure drop, pressure instability,and heat transfer enhanced effects between the plane and the porous microchannels evaporator are made.Finally,the comparisons of heat transfer performance,pressure drop,pressure instability between two different working fluid water and R-134a in microchannels. The experiment results were substituted into the heat transfer correlations in which the surface tension force was taken into consideration.The mean average error was16.5%. Pressure drop raised by increasing heat fluxes,but did not vary with increasing mass flux.The experiment results were substituted into the separation model incorporating surface tension force. The mean average error was 21.3%. The pressure drop oscillation suggested that the presence of instability inside plane microchannels as well as the maximum amplitude of oscillation were found near the onset of nucleation. The porous microchannel evaporators were sintered under the following parameters: the powder diameter dp ranged from 1~100μm, thickness of porous structure δ ranged from 225~375μm, and δ/dp ranged from 3~20, respectively. The investigation on the effect of particle size dp as well as thickness δ indicated that the ratio of the thickness to the particle size δ/dp had a significance in the heat transfer performance. This ratio must be properly chosen in order to reach a better heat transfer performance. The better ratio of δ/dp was between 3~4 in our work,withδ 225μm and dp 53μm.The average heat transfer coefficient enhanced about 3 times larger than the plane microchannels. For the porous microchannels evaporator,the heat transfer results different from the plane microchannels evaporator,heat transfer coefficient varied with varing mass flux.Pressure drop in porous microchannel evaporator was raised by increasing heat fluxes.The pressure drop was higher than plane microchannels;however,the maximum pressure drop was not over 50%. The maximum amplitude of oscillation was 66% lower than plane microchannels.This result presented that the porous microchannels evaporator provided a stable boiling behavior when nucleation began. For the porous microchannels: Working fluid water,the better ratio ofδ/dp was between 3~4;however, the better ratio ofδ/dp was between 8~12 when R-134a as working fluid.Surface tension force was probably the different choose between the better ratio ofδ/dp .The comparisons between two different working fluid water and R-134a in microchannels: The pressure results showed that water in the plane microchannels,its maximum amplitude of oscillation was larger than R-134a.The maximum amplitude of oscillation was obviously lower than the plane microchannels in two different working fluids. To conclude the present study, the porous microchannel evaporator is highly potential for the industrial applications

An experimental study is carried out here to explore possible enhancement of FC-72 flow boiling heat transfer over a small horizontal heated copper plate by two different active-like passive augmentation methods and by slight inlet liquid superheating. In the first part of the study, movable fine copper strings are installed above the plate. Specifically, parallel strings of uniform size and pitch with their ends only fixed at the plate edges are placed normal to the upstream flow direction. In this part of the experiment, the imposed heat flux is varied from 0.1 to 11 W/cm2, the diameter of strings from 79 to 254 μm, string-heated surface separation distance from 0 to 1.0 mm, and the length of the strings from 10 to 12 mm with the pitch of the strings fixed at 1.0 mm for the FC-72 mass flux maintained at 300 kg/m2s. In the second part of the study, small plastic beads like thick circular rings are mounted additionally on the fine copper strings, in addition. The beads can be irregularly rotated by the shear force from the boiling flow and by the buoyancy of the bubbles. In the test, the chosen reference beads have average outer and inner diameters of 1.45 and 0.65 mm, respectively, and thickness of 1.0 mm. The average weight of a bead is 0.0038 g. Straight parallel strings of the beads at selected pitch and height are placed above the heated plate normal to the incoming upstream flow with their ends fixed at the rig installed near the plate edges. The effects of the relevant parameters on the saturated and subcooled FC-72 flow boiling heat transfer enhancement, including the imposed heat flux, string pitch, number of beads on each wire, and bead-plate separation distance, are examined in detail. In the third and final part of this study, the inlet liquid superheating is controlled by the auxiliary heater which is installed at the upstream diverging portion of the channel. Meanwhile, the pressure in test section is maintained at saturated state. Besides, combination of the installation of copper strings and beads with the inlet liquid superheating to enhance boiling heat transfer is also examined. The experimental data obtained from the first part of the study for the installation of the copper strings show that installing the fine copper strings above the heating surface can enhance the FC-72 flow boiling heat transfer coefficient up to about 30% over that for a bare surface for a well selected set of the experimental parameters. Besides, the string size and length exhibit nonmonotonic effects on enhancing the boiling heat transfer due to complex influences of the strings on the bubble dynamics near the heating surface. Moreover, the presence of the strings is found to increase the size of nucleation bubbles and active bubble nucleation site density but meanwhile impede the bubble departure from the boiling surface. In the second part of the study, the experimental results indicate that the bubble pumping away from the heated surface from the rotating beads can effectively enhance the boiling heat transfer in the saturated and subcooled flows. Besides, the enhancement in the boiling heat transfer is more pronounced when the beads are placed closer to the plate at the medium string pitch. Moreover, there exists an optimal number of beads threaded on each wire. The best enhancement in the saturated boiling heat transfer coefficient in this study can be as high as 55 % for a suitable selection of the experimental parameters. The corresponding best subcooled boiling heat transfer enhancement is 50%. Moreover, the rotating beads can substantially reduce the wall superheat required for incipient boiling in both saturated and subcooled flows. This is particularly beneficial for electronics cooling. Finally, it is noted from third part of the present study that a slight inlet liquid superheating can be very effective in enhancing the FC-72 boiling heat transfer. The significant enhancement is found to mainly result from the increasing the bubble departure size and frequency at increasing liquid superheating. The best boiling heat transfer enhancement can be around 100% for the inlet liquid superheating of 1.2℃ and 1.5℃.
