Abstract:

Centrifugal nozzle is an important part of an areoengine in which fuel atomization has strong influence on engine performance. For investigating the fuel spray characteristics, a promising method named off-axis particle holographic measuring system is used here. Characteristics of the nonevaporating spray ejected from a new type of centrifugal nozzle which would be used in the near future are obtained under various injection conditions. By automatic analysis of the holographic reconstructed droplets images, a hollow-cone shape spray with most droplets concentrated in the surface of the cone is observed, and the spray cone angle, droplet sizes and their spatial locations in concerned region are obtained quantitativly. In the near region of the nozzle exit, droplets show greater SMD value, while at a certain distance from the nozzle, the droplets SMD differences become unconspicuous which shows a better atomization. These informations are helpful to understand characteristics of the centrifugal nozzle and offer a database for validating the spray simulation code.

Abstract:

In the present study, the effect of microstructure on the wear characteristics of spray cast Al-15Si and Al-20Si alloys has been investigated and compared with that of vertical axis centrifugal cast and chill cast alloys. The spray cast alloys have been subjected to Hot Isostatic Pressing for porosity reduction. HIPing has reduced the porosity in the spray cast Al-15Si and Al-20Si alloys from 19% to 8% and 19% to 2% respectively. The microstructures of spray cast alloys consisted of finely divided globular shaped Si particles with sizes varying from 2–10 µm. The Si particles have been distributed uniformly throughout the Al matrix. On the contrary coarse and segregated microstructures have been observed in vertical axis centrifugal cast and chill cast alloys. The sizes of primary and eutectic Si in vertical axis centrifugal cast alloys are smaller than that in chill cast alloys. The wear rates are the lowest for spray cast alloys and highest for chill cast alloys over a wide range of sliding velocity. The reasons for better wear resistance of spray cast alloys have been discussed in the light of the microstructural features evolved during spray casting.

Abstract:

This paper deals with the interaction mechanism between in situ Nb2C-V2C nanoparticles and solid/liquid interface during the rapid solidification of Fe-Nb-V alloy ribbons. In situ Nb2C-V2C nanoparticles reinforced Fe alloy matrix composite were carried out by in situ reaction and melt spun with a high-speed centrifugal spray. According to the setting of a force balance for the in situ nanoparticles in front of the S/L interface during the high-speed centrifugal spray of Fe-Nb-V alloy melt as following: F = Fbuoyant force + Frepulsive + Fviscous force + Fcentrifugal force, authors get the critical velocity that S/L interface engulfs particles is proportional to the radius of particles. TEM observation indicates that the less the size of particle is, the more easily S/L interface engulfs particles.

Defesa: Curitiba, 07/07/2009<br>Bibliografia: fls. 146-150<br>Área de concentraçao: Engenharia e ciencia dos materiais<br>Resumo: Este trabalho trata do estudo de atomizadores mecânicos–centrífugos utilizados em sistemas de injeção eletrônica de combustíveis para motores de combustão interna. Foram estudados injetores para motores do tipo à centelha, que operam segundo o ciclo termodinâmico OTTO. Através de uma abordagem teórico-experimental estudouse o fenômeno da atomização responsável pela geração do spray em njetores. O mecanismo de formação de sprays caracteriza-se pela turbulência, quebra das forças de tensão superficial, formação de filmes instáveis, ligamentos, gotas e finalmente gotículas. À luz da mecânica de fluidos aplicada e da observação dos fenômenos envolvidos em cada fase da atomização, buscaram-se correlações e modelos matemáticos de predição das principais características do spray, especialmente o diâmetro estatístico das gotículas e seu campo de velocidades. A disponibilização dessas ferramentas matemáticas é contribuição efetiva não somente à melhoria desses dispositivos, mas também à simulação da vaporização do líquido e formação da mistura carburada em motores. A literatura afirma a relação entre o desempenho do sistema de injeção com a economia de combustível e a redução de emissões poluentes. A abordagem se prima pela exploração da experimentação científica em que foram utilizadas técnicas qualitativas e quantitativas de medição do tamanho de gotículas e sua velocidade. Além de técnicas otográficas sofisticadas como a de alta velocidade, empregaram-se métodos de medição ópticos avançados a raios Laser como a velocimetria por efeito Doppler (LDV) e medição do diâmetro por diferença de fase (PDPA). O planejamento de experimentos, bem como o tratamento de resultados, valeu-se do uso de métodos estatísticos de planejamento fatorial e regressão nãolinear. Finalmente apresentam-se as orrelações como ferramentas de engenharia para projeto e melhoria de injetores. Observou-se que nas correlações para o campo de velocidades os parâmetros adimensionais mais importantes são espectivamente os números de Euler, de Weber e Reynolds, nesta ordem. Finalmente apresenta-se uma análise da influência de cada parâmetro e a aplicabilidade das correlações propostas.<br>Abstract: Among all modern human activities with impact on the environment the most important is the fuel based transportation. Regulatory guidelines for greenhouse gases "GHG" emissions and vehicle efficiency have come up in many countries after the Kyoto protocol agreement. Because of fuel availability, price rise and emission control the goal of having a more efficient engine has became a must worldwide over the last ten years. In such a scenario alternative fuels like ethanol have returned on discussion again because of its successful use. In internal combustion engines a better atomized spray is one of the key features to chieve an efficient fuel-and-air mixture in the cylinder inlet. The injection system should keep a good spray pattern and overall performance. In conventional spark engines the spray is commonly generated by injectors with pressure or pressure-swirl atomizers in the fuel outlet. The present work focus on pressure-swirl atomizers used in modern electronic fuel injection systems for spark engines. By means of a heoretical-experimental approach, applied fluid mechanics and a statistically based testing programme the atomization process in injectors is studied. This work seeks a predictive mathematical statement for the relationship between the upstream liquid properties and the operating conditions with the spray main characteristics such as the droplet size and velocity field. Such an experimental approach demands injector’s selection, test rig design and construction, spray sizing methods, research and adjustment. The experimental approach is based upon two spray evaluation techniques: a qualitative evaluation, such as high speed photography and a non-intrusive quantitative method by Laser Doppler Velocimetry (LDV) for the spray velocity field and the Phase Doppler Particle Analyser (PDPA) for droplet sizing. Finally the predicting models are presented as an engineering tool for the design and development of fuel injectors because their importance for fuel consumption and emission control.

Abstract:

Abstract Gas turbine disks made from nickel-base superalloys are often produced using powder metallurgy (P/M) techniques because the alloy compositions normally used are difficult or impractical to forge by conventional methods. This chapter discusses the P/M process and its application to superalloys. It describes the gas, vacuum, and centrifugal atomization processes used to make commercial superalloy powders. It explains how the powders are consolidated into preforms or billets using hot isostatic pressing, extrusion, or a combination of the two. It also provides information on spray forming and consolidation by atmospheric pressure, and includes a section on powder-based disk components, where it discusses the general advantages of P/M as well as the effects of inclusions, carbon contamination, and the formation of oxide and carbide films due to prior particle boundary conditions. The chapter concludes with a detailed discussion on mechanically alloyed superalloy compositions, the product forms into which they are made, and some of the applications where they are used.

Abstract:

An oil from Pacific krill (Euphausia pacifica) has a high content of PUFAs and phospholipids. The sediment was formed with homogenization of krill oil and maltodextrin (MD; dextrose equivalent (DE) = 19) solution using sodium caseinate, gum arabic, hydrolyzed whey protein or modified starch as a surfactant. Quillaja saponin could form the emulsion without the sediment. MD (28.5 wt%) was solubilized with distiller water (50 wt%) and mixed with krill oil (20wt%) and Quillaja saponin (1.5 wt%). The homogenized solution was spray-dried using Okawara-L8 spray dryer with a centrifugal atomizer. Spray-dried powder was evaluated in the oil-droplet size and surface-oil content.

Abstract:

Pumping medium containing gas has a negative impact on the centrifugal pump on mechanical properties (such as vibration, noise) and hydraulic performance, but also affect the accuracy of hydraulic test. in the GL2008-01 open letter, the United States Nuclear Regulatory (NRC) requires that some safety systems shall take into account the adverse effects of gas and the American Institute for Nuclear Research (NEI) and the Electric Power Research Institute (EPRI) pointed out the American Institute for Nuclear Research (NEI) and the Electric Power Research Institute (EPRI) pointed out that the gas in suction side shall not exceed the limit of 2% (volume ratio). In HPR1000, the 3rd generation reactor, it is the first time proposed that some systems are with long-term gas entrainment condition, and there is up to 3% (volume ratio) free gas in the horizontal centrifugal Spray Pump suction side water. In order to study the 3% gas entrainment condition effects on the hydraulic performance of Spray pump, a way is found to calculate the head drop by some equations and carried out a containing free gas hydraulic test. The results show that under the 3% gas condition, Spray pump head is 0.60% dropped by equation calculation and 0.66% dropped by test, comparing with no gas condition. The 3% gas effects on the Spray pump performance are very small. The reasons is that the structure of the Spray pump is well for vent during operation and the gas is not accumulate in the pump, so the performance of the pump has no effect.
