<p>Two-phase flow loop cooling system is required for increasing heat transfer rate, heat transport distance, and cooling heat flux in thermal control of space structures. The understandings on thermo-fluid dynamics of gas-liquid two-phase flows with phase change under microgravity is necessary for the system design. To clarify the phenomena and verify the operation of two-phase flow loops under microgravity condition, two-phase flow loop experiments were conducted as a JAXA project named TPF experiment onboard the International Space Station (ISS). The loop was a pump-driven loop and the pressure was maintained by an accumulator. Perfluorohexane was used as the working fluid because of low latent heat of vaporization and moderate boiling point under the restriction of power input and for the safe operation. The loop had two kinds of heating section, such as a copper heating tube and a transparent glass heating tube, and a condenser. Flow observation sections made of transparent polycarbonate resin were installed just downstream of each heating tube in order to observe and measure the interface structure of boiling two-phase flow in detail. In this report, the design concept and system characteristics of the experimental loop and the results of the gas-liquid two-phase flow measurements in the flow observation section are presented.</p>

Recent increase in the size of space platforms requires the management of larger amount of waste heat under high heat flux conditions and the transportation of it along a long distance to the radiator. Flow boiling applied to the thermal management system in space attracts much attention as promising means to realize high-performance heat transfer and transport. However, gravity effects on the two-phase flow phenomena and corresponding heat transfer characteristics have not yet been clarified in detail. In the present paper, flow boiling heat transfer characteristics are investigated in the microgravity environment by the parabolic flight experiments.

Abstract;The paper presents an experimental verification of the theoretical analysis for thermally-induced structural responses of a rolled-blanket-type solar array subjected to sudden radiation heating such as typical night-day transition in orbit. Experiments were conducted using one-tenth model of asymmetric Flexible Rolled-Up Solar Array of the Hubble Space Telescope. The model was composed of a blanket, two flexible booms, and a rigid spreader bar. Time histories of tip deflections of two booms were measured. Quasistatic components of the deflections were in good agreement with the theoretically predicted results. Measured surface temperatures of the booms were also presented. (author abst.)

The standard test methods for an interlaminar fracture toughness of composite materials by JIS and ASTM are prescribed based on the linear fracture mechanics. However, when the fracture toughness tests are performed on a toughened carbon/epoxy composite, a local matrix yielding occurs at the crack tip and the crack initiation and growth behavior are affected by the material nonlinearities. In this study, we evaluate the effects of the local matrix yielding on the mode-II interlaminar fracture toughness properties of a toughened CFRP.

Much attention is focused on boiling and two-phase flow for the improvement of cooling and heat dissipation processes on the ground and in space. The development of high-performance thermal management systems in space is required for the future space missions with a large energy consumption under the condition of minimized size and mass of cooling systems. However, there is a limited number of experimental data needed for the design of the system, though .the flow and thermal characteristics depend on gravity especially at low mass velocity and/or low vapor quality. Flow boiling experiments has started onboard “KIBO” in ISS as a joint project with JAXA since 2017. In the present paper, the objectives and contents of the experiment are clarified and individual subjects to be clarified are explained including the optimized structures of the test sections. In addition, the present situation of preliminary experiments is reported.

Heat transfer characteristics were investigated for pool boiling of immiscible mixtures on a flat heating surface of 40mm in diameter facing upwards. Experiments were conducted at 0.1MPa and volume ratio of more volatile component and less volatile component is changed as a key parameter. Increase of critical heat flux was observed and its maximum value was 3.04×106 W/m2 for FC72/Water mixture, and also the reduction of heating surface temperature from the value for pure water was confirmed at high heat flux for small volumetric ratio of FC72. We conclude that this improvement is due to the self-sustaining subcooling peculiar to the boiling of immiscible mixtures.

Flow boiling systems attract much attention for the cooling of electronic devices with large heat generation and its density. In the present study, flow boiling experiments are conducted for the combination of FC72 and water as an immiscible liquid flowing in a circular tube. Various flow patterns are observed by the combination of both flow rates even under unheated conditions. A method is devised to predict the distribution of liquid temperature under vaporization process for the evaluation of local heat transfer coefficients. From the experimental results, flow patterns under unheated conditions have strong influence on the heat transfer characteristics. Convection of water is enhanced for the emulsion-like flow under low heat flux conditions when the flow rate of FC72 is low.

The understanding of two-phase flow dynamics under micro gravity is necessary to design a two-phase flow loop type thermal control system for space structure. Experiments at JEM "Kibo" in the international space station are planned. In this paper, void fractions were measured by capacitance method to clarify two-phase flow characteristics of FC-72 which is used as the working fluid in the ISS experiment. Measured results of average void fraction agreed well with the correlations based on drift-flux model. On the other hand, flow pattern transitions agreed well with those by Mishima-Ishii.

情報化社会の発展に伴う電子機器の高性能化と小型化がもたらす発熱密度の増大により，電子機器の冷却は重要な課題として認識されている．このことは宇宙機器に取込まれる半導体においても近い将来に問題になることは必至である．このため，沸騰による潜熱輸送によって高い熱伝達効率を可能とする二相流体ループを用いた冷却システムに注目が集まっている．
　また，プール沸騰実験により，低沸点液体と高沸点液体の密度の大小関係とその成分比を最適化した場合，沸騰冷却に非共溶性混合媒体を用いることで，次の利点があることを確認した．
(1) 限界熱流束の増大
(2) 伝熱面表面温度の低減
(3) 沸騰開始時の伝熱面温度のオーバーシュートの緩和
　そこで，非共溶性混合媒体をポンプ駆動の排熱ループに適用した地上用および宇宙用の冷却システムの開発を目的とし，実験により強制流動沸騰熱伝達に関する基礎的な知見を得る．

高発熱密度の半導体素子の高効率冷却を目的として、30mm×30mmの発熱体をターゲットとし、沸騰二相冷却による直接液冷技術の適用について研究開発を行った。冷媒はNovec7100に界面活性剤を介して1.17vol%のナノ水滴を分散させた液体を使用し、伝熱特性および冷却性能について評価した。主流路間隙幅2mm、補助給液口38mm2×2列の断面積を有する副流路付溝付伝熱面構造の冷却ジャケットを水平に配置し、試験圧力0.15MPaで強制流動沸騰の試験を実施した。入口液体サブクール度30K、体積流量0.6ℓ/minの条件で、限界熱流束3.5×10^5W/m^2（315Wに相当）の結果が得られた。この時、熱伝達係数は7.2×10^3W/m^2Kで、伝熱面表面温度は107 ˚Cであった。試験液体としてNovec7100純媒体を使用した同条件での試験では、限界熱流束は2.6×10^5W/m^2（234W）であり、約1.35倍の除熱能力の増大が確認できた。なお、これ以外の本試験範囲では、入口液体サブクール度35K、体積流量1.0ℓ/minの条件で、限界熱流束4.9×10^5W/m^2（441W）、熱伝達係数8.0×10＾3W/m^2K、伝熱面表面温度110 ˚Cが得られており、耐熱温度の低いSi素子等の冷却用としては圧力調整による流体温度の低減などの改善を要するが、現状でもSiC等の高発熱密度半導体素子の冷却としての適用は十分可能と結論される。伝熱面表面およびナノ流体の性状に、伝熱面上には若干のスス状の堆積物や流体の透明度が変化するという状況が観察されたが、際立った伝熱劣化は確認されていない。なおナノ流体の熱伝達係数については、Novec7100純媒体との大差は無く、試験条件によっては、Novec7100純媒体の方が僅かに高い場合もあった。今後、異なる成分のナノ流体や別の混合媒体を使用するなどして、さらなる熱伝達係数の向上および伝熱面表面温度の低減の可能性について検討することが必要である。

微小重力下での沸騰熱伝達機構を定性的かつ定量的に解明するために、気泡挙動、局所熱伝達および重力レベルの関連性を時系列データより調べる。このため、気液挙動観察や局所熱伝達評価が可能な透明伝熱面を開発し、2008 年11 月にESA パラボリックフライトキャンペーンを利用した微小重力下でのプール核沸騰実験を実施した。実験により得られた伝熱面局所表面温度と加熱量を用いて伝熱面局所熱伝達係数を求め、気液挙動と熱伝達の関係、核沸騰熱伝達へのサブクール度の影響および重力レベルの変動による熱伝達特性の変化について調査した。

高密度発熱源を有するサーバラック内は局所的な温度分布が顕著であり、かつサーバルームには狭い間隔でラックが詰め込まれているため、ラックの消費電力量の1.2～1.3倍もの電力が必要な空調設備となっているのが現状であり、液体冷却方式の採用は近い将来必要不可欠である。沸騰・二相流冷却を適用するために側面副流路配置狭あい流路構造の冷却ジャケットおよび半導体素子を模擬した発熱体（30mm×30mm）を冷却するための試験ループの試作を行い、実験による性能評価を行った。複数台の冷却対象が存在する場合の冷却システムについて検証するために、基板上に設置した3台の模擬発熱体を並列的に冷却するような試験ループの試作を行い試験した。体積流量0.6 l/min、入口液体温度39℃（入口液体サブクール温度33K）の条件において、全てのテストセクションで300Wの除熱を達成した。
