    The present paper reports on the effect of 3D-oriented particles on birefringence using the concept of 'rheooptics', a technique for identifying changes in the internal structure or flow dynamics of complex fluids from changes in optical anisotropy (birefringence). We used the photoelastic method, as a kind of polarized light imaging technique, to visualize the internal orientation structure induced by applying shear stress to cellulose nanocrystal (CNC) suspensions under shear flow. Two different rheometers (concentric cylinder and parallel plate-type) that can easily combine a birefringence measurement system were introduced to Transverse rotation Longitudinal rotation perform the shear flow induction, and the birefringence was measured and compared from vertical and horizontal directions for shear. The birefringence measurements from different directions provide an opportunity to investigate the effect of 3D-oriented CNCs on birefringence, which is a novelty of the present study. The measured birefringence was fitted with the empirical equation proposed in the previous study and followed the power law of applied shear rate with the same exponent, independent of the shear direction at the time of measurement This result suggests that there is a common physical background that gives birefringence a power law. This exponent was different from the values given in previous studies and is explained by differences in the particle interaction behaviour based on the concentration of suspensions and CNC length. Note that the proportionality coefficients differ by a factor of 10, clearly indicating differences due to the direction of birefringence measurement. These results indicate that birefringence due to transverse rotation of the CNC is more sensitive to shear stress than to longitudinal rotation.

    The control of the velocity of a high-speed laser-induced microjet is crucial in applications such as needle-free injection. Previous studies have indicated that the jet velocity is heavily influenced by the volumes of secondary cavitation bubbles generated through laser absorption. However, there has been a lack of investigation of the relationship between the positions of secondary cavitation bubbles and the jet velocity. In this study, we investigate the effects of secondary cavitation on the jet velocity of laser-induced microjets extracted using explainable artificial intelligence (XAI). An XAI is used to classify the jet velocity from images of secondary cavitation and to extract features from the images through visualization of the classification process. For this purpose, we run 1000 experiments and collect the corresponding images. The XAI model, which is a feedforward neural network (FNN), is trained to classify the jet velocity from the images of secondary cavitation bubbles. After achieving a high classification accuracy, we analyze the classification process of the FNN. The predictions of the FNN, when considering the secondary cavitation positions, show a higher correlation with the jet velocity than the results considering only secondary cavitation volumes. Further investigation suggested that secondary cavitation that occurs closer to the laser focus position has a higher acceleration effect. These results suggest that the velocity of a high-speed microjet is also affected by the secondary cavitation position.

    In the motion of two spherical bubbles rising side by side, the bubbles are known to attract each other at a high Reynolds number (Re = ρUd/μ). Furthermore, spherical bubbles kiss and bounce under certain conditions; however, deformable bubbles repel each other without kissing. This paper experimentally and numerically presents the flow structures and shape of the nonkissing repulsion of deformable bubbles. For the experimental analysis, we organized bubble behaviors by Galilei number (Ga = ρg1/2d3/2/μ) and Bond number (Bo = ρgd2/σ). The bubbles repelled each other without kissing near the unstable critical curve of a single bubble. The curvature inside the gap, which is similar to the shape of a zigzag behavior bubble, was large. For the numerical analysis, the velocity of the equatorial plane inside the gap was larger due to the potential interaction, although the velocity behind was the opposite due to the strengthened vorticity generated at the surface. Furthermore, the double-threaded wake emerged behind the interacting bubbles, and it showed that the rotation direction was repulsion regardless of whether the bubbles attracted or repelled each other. The streamline behind the bubbles in the 2D plane was from the outside to the inside.

  • Effects of Tube Length and Boundary Condition on the Bubble Generation Method Using Acoustic Pressure Wave in Gas Phase Reviewed

    A bubble generation method that uses a slit elastic tube and an acoustic pressure wave in the gas phase can produce single bubbles of various sizes. In the method, the bubble size greatly depends on the tube length and the boundary condition of the tube end. In this study, we investigated the effects of acoustic pressure waveforms on the bubble generation. We changed the tube length and the boundary condition of the tube end and measured the waveform using the electret condenser microphone (ECM) and the generated bubble diameter. The time length that the positive pressure was maintained on the waveform depends on the tube length and the boundary condition. The diameter of the generated bubble also changed with the time length. We demonstrated that this phenomenon was caused by the change of the phase of reflected wave at the tube end by using FDTD simulation.

  • Influence of Surfactants on the Motion of a Pair of Bubbles in Quiescent Liquids Reviewed

    We experimentally investigated the motion of a pair of bubbles initially positioned in-line configuration in ultrapure water or an aqueous surfactant solution. The bubble motion was observed by two high speed video cameras. The Reynolds number of bubbles were ranged from 50 to 200, and the bubbles hold a spherical shape in this range. In ultrapure water or small concentration of surfactant solution, initially the trailing bubble deviated from the vertical line on the leading bubble owing to the wake of the leading bubble. And then, the slight difference of the bubble radius changed the relative motion. When the trailing bubble slightly larger than the leading bubble, the trailing bubble approached to the leading bubble due to it s buoyancy difference. The bubbles attracted and collided only when the bubbles rising approximately side by side configuration. On the other hand, the trailing bubble was drafted to the wake region of leading bubble when the bubbles were rising in high concentration of surfactant solution. In this case, the bubbles always collided in line configuration. We consider that these phenomena are caused by the changes of lift force direction in the wake region owing to the surface contamination. In addition, bubble coalescence was inhibited in surfactant solution, even the relative motion was similar to the clean bubble case.

  • Experimental investigation of the motion of a pair of bubbles at intermediate Reynolds numbers Reviewed

    For the problem of bubble-bubble interaction at intermediate Reynolds numbers, some theoretical models and direct numerical simulation results are available
    however, experimental verifications are lacking. In this study, we observed the motion of a pair of bubbles, produced by an originally developed bubble generator, interacting in-line. The Reynolds numbers of the target bubbles ranged from 50 to 300. The bubble motions were observed using two high-speed video cameras, and their diameters were measured by a high-resolution digital still camera. Initially, the lift force acts on the trailing bubble owing to the wake of the leading bubble
    the lift force causes the trailing bubble to deviate from the vertical line to the leading bubble. The potential interaction then becomes dominant. Finally, the trailing bubble approaches the leading bubble. This motion is completely different from the particles motion in which the trailing particle is drafted toward the wake region of the leading particle. In addition, it is shown that a slight difference in the diameter of the bubbles drastically changes their interaction.

    ２つの気泡間相互作用メカニズムを明らかにするため，本年度は実際の変形を考慮して3次元的に水平方向に並んで上昇する２気泡について数値解析を行い，その挙動を調査した．また，気泡周りの流動構造を調査し相互作用のない単一気泡周りの流れおよび球形を仮定した２気泡周りの流れと比較検証を行った．本研究の内容は学会および論文掲載を通して行った．
    １．数値解析の結果から従来通りアスペクト比が小さく球形に近い気泡同士には引力が働くことを確認した．しかし，扁平した気泡には斥力が働くことを確認した．気泡のパラメータがzigzag螺旋運動など不安定挙動を行う領域ではその斥力がはっきり出現するが，扁平が進みさえすれば不安定挙動領域でなくとも気泡同士は近づかないことを明らかにした．
    ２．気泡の後部にできる渦対は気泡運動を決定する重要な因子であると考えられている．しかし，水平方向に並んでいる気泡では，実際の相互作用が引力・斥力に関わらず，渦対自体は斥力を示す．従って，球形気泡では渦度起因の斥力が弱く，ポテンシャル流によって予測される相互作用によって気泡間の圧力が低下し引力が働いた．一方で扁平気泡では気泡の最大曲率が増加し，それによって気泡界面で生成される渦度が大きくなるため，渦度起因の相互作用が支配的になり不安定挙動領域でなくとも反発したと予想される．
    ただし，気泡に働く揚力は小さく界面応力から導出することは困難であった．気泡相互作用のモデル化には，あらかじめ回転楕円体を仮定した剛体気泡の数値解析が必要であると思われる．
