    「線香花火の熱流動の研究」
     井上智博君は,日本の伝統的な手持ち花火である線香花火に関して様々な観点から研究を進めている。線香花火は江戸時代に日本で始まり,黒色火薬と和紙のみを使う最も基本的な花火である。井上君はこれまでの成果で,火花が飛び出し分岐する機構や,儚い色味を見せる機構を明らかにした。その中で,線香花火の律速過程は,液滴の熱伝導現象であり,液滴が連鎖的に分裂することで松葉模様が形成されることを明らかにした。線香花火の松葉に似た枝分かれした火花はカリウム化合物の溶融物の液滴であり,連続的に分裂する液滴は液滴の発熱表面反応からの継続的な熱によって自立する。そして,線香花火の液滴は,飽和蒸気圧が低いため非蒸発性であることを示した。また,比較的低温に起因する線香花火の壊れやすい美しさは,発熱量の減少と硫酸カリウムの融合という2 つの要因によって実現されていることを明らかにした。
     これらの研究成果は,長年の謎であった線香花火の科学を明らかにするものであり,伝統的な煙火の美しさの解明を今日の科学技術が紐解いた特筆すべき事例である。また,学術的にも火薬学会に大きく貢献するものであり,火薬学会論文賞に値する。

  • Viscous-capillary thinning of molten metal ligament stimulated by surface oxidation

    For producing fine metal powders, the critical step is ligament dynamics of molten metal, while the thinning and breakup processes subjected to the interfacial heat and mass transfer are elusive. Here, we conduct high-speed visualization and infrared pyrometry on a single tin ligament that enable us to distinguish the effects of surface oxidation and cooling. On the tin ligament, a thin oxide layer grows according to the molecular diffusion of ambient oxygen, leading to the significant increase of viscosity coefficient at the interface. The capillary destabilization is then suppressed by the surface oxidation. We discover that the tin ligament thins initially following the capillary timescale, while the necking is accelerated to obey the viscous-capillary timescale as the oxide layer becomes one-tenth of the neck radius, corresponding to the Ohnesorge number of larger than unity. Simultaneously, the neck is cooled by the ambient. The accelerated thinning due to the viscous effect leads to the prompt decrease of heat capacity. We successfully formulate the rapid temperature drop at the neck based on the interfacial heat transfer coupled with the viscous-capillary necking dynamics in a consistent manner.

  • Boiling induced atomization of liquid film produced by oblique jet impingement on superheated wall

    Sako, N; Hayashi, J; Inoue, C; Kawanabe, H; Daimon, Y

    For the thermal management of industrial devices, a reduction in the net coolant flow rate by droplet dispersion from a liquid film is important because it can cause unexpected thermal failure. To understand the process of droplet dispersion from a liquid film better, we experimentally and theoretically evaluated the characteristics of boiling-induced atomization in a liquid film formed by oblique jet impingement on a superheated wall. Atomization processes were visualized using magnified high-speed imaging using a backlight technique. In this study, two types of droplets were observed using high-speed-magnification imaging. These were large droplets that disintegrated from the ligament formed on a relatively high-temperature wall, and small droplets from the ligament formed via bubble bursting in the nucleate boiling regime. For the atomization induced by nucleate boiling, larger droplets were produced via bubble bursting further downstream from the impingement point because the bubble size and liquid film thickness increased. Finally, the total volume of the droplets produced by nucleate boiling was estimated from the frequency of bubble bursting and droplet size measured from the visualization results. The estimation results suggest that the ratio of the total volume flow rate of the ejected droplets to the injection flow rate of the liquid was negligible (2%). Thus, most of the injected liquid eventually reached the wetting front of the sheet, separating it from the wall before drying out.

    We perform physics-based theoretical analyses on the tradeoff between the overall performance of specific impulse and the thermal protection ability of a coolant liquid film to identify the optimal configuration of a liquid rocket engine. A bipropellant thruster is set as the target, which uses a hypergolic propellant mixture of nitrogen tetroxide as the oxidant and monomethyl hydrazine as the fuel. By considering the practical nonuniform distribution of the local mixture ratio produced in the thrust chamber, the maximum specific impulse is achieved when the fuel and oxidizer spray widths become identical, allowing for the specification of the diameter of the impinging-type injector. The heat balance between the convective heat transfer from the combustion gas and the latent heat of the three-dimensionally wavy liquid film provides the optimal diameter of the combustion chamber. The longest liquid film is found to be achieved when half of the initial film is entrained by the fast gas, correspondingly mitigating the heat transfer area due to the liquid film waviness. We successfully demonstrate the optimal architecture of the liquid engine based on the tradeoff, in which an improvement of specific impulse by 1 s shortens the film length by 2 mm.

  • Role of volatility and thermal properties in droplet spreading: a generalisation to Tanner's law

    Wang, ZY; Karapetsas, G; Valluri, P; Inoue, C

    Droplet spreading is ubiquitous and plays a significant role in liquid-based energy systems, thermal management devices and microfluidics. While the spreading of non-volatile droplets is quantitatively understood, the spreading and flow transition in volatile droplets remains elusive due to the complexity added by interfacial phase change and non-equilibrium thermal transport. Here we show, using both mathematical modelling and experiments, that the wetting dynamics of volatile droplets can be scaled by the spatial-temporal interplay between capillary, evaporation and thermal Marangoni effects. We elucidate and quantify these complex interactions using phase diagrams based on systematic theoretical and experimental investigations. A spreading law of evaporative droplets is derived by extending Tanner's law (valid for non-volatile liquids) to a full range of liquids with saturation vapour pressure spanning from to Pa and on substrates with thermal conductivity from to. In addition to its importance in fluid-based industries, the conclusions also enable a unifying explanation to a series of individual works including the criterion of flow reversal and the state of dynamic wetting, making it possible to control liquid transport in diverse application scenarios.

    To reduce the probability of unstable ignition during vacuum startup of bipropellant thrusters using hypergolic propellants, it is essential to comprehend the propellant jet within the combustion chamber from startup to ignition, in addition to the spray conditions of heterogeneous impingement. Particularly for new thruster design, understanding the atomization and mixing state and being capable of predicting ignition from cold flow tests are of utmost importance. In this research, the propellant flow during simulated thruster vacuum startup transient was visualized to clarify the mechanism of ignition delay. Moreover, the nondimensional injection condition Λ, which serves as a mixing condition index during steadystate combustion, is extended to the vacuum startup transient. As the process transitions from a vacuum to oxidizer vapor pressure, the oxidizer jet morphs into a spray condition due to flash boiling. A scenario is developed where the oxidizer sprays exacerbate the spray atomization and mixing of heterogeneous impingement as a result of interactions with the fuel, leading to ignition failure. Furthermore, by extending the nondimensional injection condition Λ into two dimensions and evaluating the correlation between the propellant distribution and Λ, it is demonstrated that the spray mixing of heterogeneous collisions can be predicted, even during the vacuum startup transient.

    A metal spark generated by grinding carbon steel has been recognized proceeding multiple bursting events, akin to the luminous branching fireworks. The mechanism of successive fragmentation observed in carbon steel spark, however, has not been elucidated yet. In the present study, we develop a new comprehensive analytical framework for estimating the droplet size of carbon steel sparks, time of flight, and time-variant temperature, combined with high-speed images of the spreading sparks, for the quantitative discussion of the timescale of bursting metal sparks. We find that the flight time to burst for a mother droplet is independent of the content of carbon, corresponding to the Fourier number for the molecular diffusion of unity. The successive fragmentation of carbon steel sparks is rate-controlled by the molecular diffusion of ambient oxygen inside the droplet. Since the measured temperature indicates that the heat is produced by the oxidation of iron, the successive fragmentation stops when the iron in the spark is fully oxidized, immediately becoming a solid particle.

    We conduct a high-speed visualization of coolant liquid film dynamics inside a 10N-class bipropellant thruster using monomethylhydrazine and a mixture of nitrogen tetroxide with approximately 3% nitric oxide as propellants at equivalent conditions with the flight model. The direct visualization of the liquid film inside a quartz glass chamber demonstrates the transient dynamics of film flow from ignition to cutoff for the first time. The scenario for the life of the film flow is found as follows: the coolant fuel jet impinges on the chamber wall being the liquid film; the friction force from the chamber wall rapidly decelerates the film as one-tenth of the injection velocity; next, the film moves sheared by the fast combustion gas downstream; and eventually the film completely evaporates by heat transfer from the hot combustion gas. The liquid film presents the typical ripple wave structure, covered by the velocity and thermal boundary layers. The effect of the mixture ratio is significant as the film flow rate increases at a small mixture ratio, leading to the longer film length.

    <p>Non-uniform distribution of interfacial mass flux across an evaporating droplet will subsequently induce a temperature gradient across the liquid-air interface, and result in thermal Marangoni stress that reforms the flow field inside the droplet. Recent study (Shiri, et al. Phys. Rev. Lett. 2021, Yang, et al. Langmuir 2022) confirmed the role of thermal Marangoni effect on the shape of evaporating single component droplets on completely wetting substrates. Nevertheless, a comprehensive evaluation of the interacting mechanisms is still lacking due to the intrinsic limitation of experimental techniques to decompose the different influence factors. To this end, we formulate a mathematical model to simulate the evaporation of volatile droplets on completely wetting substrates based on the lubrication theory. With this model, we elucidate the interacting physical mechanisms that governs the droplet kinetics during phase change, which includes the capillary effect, the thermal Marangoni effect, the interface motion due to evaporation, as well as the removal of energy barriers by precursor film. A phase diagram is summarized in terms of the Knudsen number and liquid-to-solid Biot number, which quantifies the prevalence of the interacting effects.</p>

    <p>In recent years, Additive Manufacturing (AM) technology such as 3D printing has attracted much attention. In order to produce high-quality metal powders as printing materials, it is necessary to elucidate the phenomena of liquid metal splitting accompanied by solidification, which is manifested in the powder manufacturing process. So far, various experiments have been conducted on the atomization method, but the mechanism for determining powder properties has not been clarified. In particular, there is insufficient knowledge about the phenomenon of molten metal splitting along with solidification. Therefore, in this study, we investigate the breakup process of a single ligament of 42Sn-58Bi, which is a kind of fusible alloy with a melting point of 139 ℃. A high-speed camera is used to visualize the pinch-off process of the ligament. The variation of the neck diameter of the ligament is traced during the fragmentation process. When the initial temperature is high, we found that the neck diameter thins down following a power law of 2/3, corresponding to the trend derived from capillary time scale. On the other hand, as the initial temperature gets lower, the neck diameter becomes thinner than that predicted by the capillary time scale just before breaking up, which is attributed to the influence of solidification.</p>

    宇宙機の二液式スラスタは,液体燃料および酸化剤を燃焼室内に噴射し,互いに衝突・微粒化混合することで,自発的な着火,燃焼を促し推力を得る.このスラスタの始動・停止時には燃焼室内部が真空状態となり,噴射推薬の減圧沸騰が避けらず,始動不安定につながる点が興味深い.しかし,その不安定な始動機構は長年の未解決課題である.そこで本研究では,光学系高速度計測を駆使し,減圧沸騰下の推薬混相熱流動状態を定量化および数理モデル化することで,始動・停止時におけるスラスタ性能予測技術を確立する.これにより,着火安定性を向上させたスラスタ開発に貢献する.

    近年,高温の金属液滴の内部で凝縮相反応に駆動されて発泡し,液滴が連鎖的に分裂を繰り返す,連鎖分裂現象が発見された.特に,沸点よりもはるかに低温で,凝縮相反応に起因して金属液滴内部に気泡生成する点が興味深い.しかし,その機構は流体工学上の未解決課題である.そこで本研究では,二色温度法を適用した高速温度計測と,発生ガス種のその場分析が可能な唯一の手法であるInfi-TOF(マルチターン質量分析)を同期した新しい複合分析法を用いて,まさに連鎖分裂するときの液滴温度と発生ガス種計測することで,熱流体工学の常識を超えた凝縮相の連鎖分裂機構を探究する.
