项目摘要

Micro bubbles attract a great deal of attention due to their large potential for expansion in both science and technology. Conventional measurement techniques such as PDA (Phase Doppler Anemometer), ILIDS (Interferometric laser imaging for droplet sizing) and so on are insufficient to reveal their interting and useful properties. In the case of high number density of the micro bubbles, the conventional measurement techniques are not available. For the purpose of overcoming the difficult problem and pioneering an innovative field in multiphase flows, the head invastigator proposes a new measurement system based on his research results of micro optical fiber probe. We newly developed the multifunctional photoelectric fiber probe that simultaneously measures the diameter, velocity and number density of bubble/droplet and the concentration of substances. The outline of the results as follows;1) By simultaneously using optical signals and electric signals, we established the new measurement system that measures the diameter, velocity, number density and surface potential of the micro bubbles/droplets, as well as measurement of the surface tension.2) We established micro fabrication of quartz by femtosecond pulse lasers.3) We elucidated the change of dynamical properties of micro bubbles/droplets and the changes of interaction between them and the surrounding phase owing to expression of function. We obtained the data for application in material production.4) We obtained basic data for micro fabrication of tiny optical fibers and established the techniques for the micro fabrication.The products during the three-year study period are listed below:1) 30 papers (4 papers in Japanese journals and 24 papers in international journals),2) 24 papers in international conferences3) 17 invited keynote lectures (international conferences)4) 24 invited keynote lectures (domestic conferences)5) 3 patent applications (2 patents applied to Japan and 1 patent applied to oversea countries)

微气泡由于其在科学和技术方面的扩展潜力而引起了很大的关注。常规的测量技术，例如PDA（相多普勒风速计），ILIDS（用于液滴尺寸的干涉测量激光成像）等不足以揭示其交织和有用的特性。在微气泡数量高密度的情况下，不可用的常规测量技术。为了克服困难问题并开创了多相流中创新的领域，头部侵入剂基于他的微光纤探针的研究结果提出了一个新的测量系统。我们新开发了多功能的光电纤维探针，该探针同时测量了气泡/液滴的直径，速度和数量密度和物质浓度。结果的概述如下：1）通过使用光学信号和电信号，我们建立了新的测量系统，该系统测量了微型气泡/液滴/液滴/液滴的直径，速度，数量密度和表面电位，以及表面张力的测量。由于功能的表达，微气泡/液滴以及它们之间的相互作用变化与周围相。我们获得了用于在材料生产中应用的数据。4）我们获得了微型制造微小光纤的基本数据，并确定了微制造的技术。在下面列出了三年研究期间的产品：1）30篇论文（4篇论文（日本期刊中的4篇论文）（国际期刊中的24篇论文），24篇论文，2）24篇国际会议的序幕4邀请了44张国际宣传（17）（International Contrice 3）（邀请了4）（邀请4）（邀请4）（邀请了4）（邀请4）（邀请了4）（LECTERIEN）（邀请了4）（LECTER）。讲座（国内会议）5）3 3项专利申请（对日本申请了2项专利，并适用于海外国家的专利）
