液体ヘリウム(He)は絶対温度2.17[K]において相転移をおこし、粘性の無い超流動成分が出現する。超流動成分中には循環を伴う量子渦が存在するが、渦軸まわりには粘性のあるHeを付随している。この構造は古典乱流（水や空気の流れ）中の微細渦と類似している。本研究では両者の類似性に着目し、超流動流れの乱流を古典乱流の知見を介して統一的に解釈することを目的とする。超流動風洞を用いて定常な流れを作り、画像速度計測法から変動速度を算出して速度普遍則の存在と渦の階層構造を定め、量子乱流場の特徴づけをおこなう。

量子乱流場は、超流動と常流動成分が混在する複雑乱流場である。常流動成分は水や空気の流れと同様に粘性乱流としてふるまい、乱流中には微細な渦構造(乱流渦)が存在する。一方、超流動成分中にも量子渦と呼ばれる旋回を伴う渦構造が存在する。本研究では、新たな可視化粒子としてヘリウムエキシマを用いる。エキシマはヘリウム原子に電子を衝突させることで電荷を持たせ、別のヘリウム原子と結合した状態である。エキシマの生成には放射線（中性子、ガンマ線）及びプラズマ発光を利用する。エキシマによる流動場可視化と量子渦の運動を定量化することで複雑乱流の新たな知見を得ることを目的とする。
大強度陽子加速器施設(J-PARK)において、液体ヘリウムに中性子を照射させ、ヘリウムエキシマの生成実験をおこなった。三重断熱構造のクライオスタットにヘリウムを収め、減圧することでλ点(2.17K)以下に設定した。中性子を照射することで生成されたヘリウムエキシマをパルスレーザー(905nm)により励起状態として、その発光を観測することに成功した。発光は極めて微弱であるため、新たにイメージインテンシファイアを設置して輝度を増幅し、加えて高感度カメラでの計測をおこなった。
パルスレーザーの発振周波数を撮像系（イメージインテンシファイア＋高感度カメラ）と同期することでエキシマ発光を効率的に撮像した。また、昨年度までの研究から、レーザー照射からエキシマ発光まで微小な時間差があるため、その時間差を撮像系に加味することで、発光強度の高い画像が撮影できた。高感度カメラの輝度が飽和しないように事前の調整をおこなう必要があった。
ヘリウムエキシマは、クラスター構造を形成することが予想されており、その大きさは100μm程度である。本研究では、可視化画像の解析から同程度の大きさを持つ発光領域を観察できており、クラスター構造が中性子照射によって形成されることを初めて確認できた。今後は、発光領域の大きさの頻度分布、その継続時間を定量的に解析する必要がある。エキシマの発光時間は、脱励起過程が効率的におこなえれば10秒程度と見積もられており、時間的減衰の過程も調べる予定である。
データ解析の方法について、クラスター構造を時間・空間で検出するアルゴリズムを開発している。ほぼ完成しているが、より定量的な基準を策定する予定である。
中性子照射により励起されたヘリウムはエキシマ構造を持ち、特定の波長で励起することでエネルギー準位をあげ、その後、発光することを確認できた。しかし、発光は散乱角を考慮すると、特定方向に設置したカメラで継続的に計測できるわけではない。発光をくり返すエキシマの発光強度の時間的減衰を調べることで、エキシマが生成される頻度を算定する。エキシマクラスターが、空間内をどの様に移動するのかを定量的にしらべ、移動速度とクラスター形状の変化を調べる予定である。エキシマクラスター構造の発生する兆候を明らかにしたい。

The piezoelectric material is BGO, which has a surface wave sound velocity similar to that of water, and a unidirectional type circuit is used to develop an acoustic flow radiation type flow field control device that can radiate acoustic flow in one direction at an angle of about 30 degrees from the wall surface. The V-shaped electrode type shear force meter was developed to evaluate not only the absolute value of shear force but also the direction of shear force by forming a rectangular electrode and arranging it in a V-shape.
By combining these devices, flow field control experiments were conducted in a channel flow. V-shaped electrode shear force gauges were installed on the upstream and downstream sides of the acoustic flow control device to measure the shear force during flow field control. In some cases, the shear force decreased both upstream and downstream of the acoustic flow control device, confirming that the flow field control can reduce drag.

An international collaboration with PTB (Physikalisch-Technische Bundesanstalt, Germany) was conducted to clarify the universality of the pipe friction factor and mean velocity profile in high Reynolds number pipe flow. As a result of the measurement of the pipe friction factor and the mean velocity profile, a very high agreement was successfully obtained for both. The universal value of the pipe friction factor and the universal profile of the mean velocity in a pipe flow were clarified. The physical reason for the Superpipe's value in the previous study was found to be the velocity profile in the wake.

The measurement system of three velocity components of fluid flow in space is realized with four high-speed cameras and CW laser. Small-scale turbulent structures and vortex sheet are captured by the Q-criteria based on velocity gradient tensor. Small particle trajectories in super fluid were analyzed and they are characterized by the local curvatures. It was found that the PDF of curvature is similar with that of classical turbulence. However, it differs between two and three dimensional space. The local curvature can also characterize the interaction of particles with quantum vortex. The separation distance between quantum vortexes can be estimated by the variance of particle position along the trajectories and Hurst exponent. As a new visualization system, it was confirmed that the helium excimer can be used as tracer particles in super fluid which is generated by the discharge in liquid.

The three-dimensional visualization system was constructed with 4 high-speed cameras. And the Lagrange trajectories are recorded in a short period of time. The camera system, small luminescence particles, laser system, and optical systems were improved. This visualization system enables us to obtain the velocity filed in space and the small eddy structures are visualized by means of 2nd invariant of velocity gradient tensor. For applying to the visualization of quantum eddy, each camera is connected with one another by ran cables and is synchronized by trigger input signal. Small particle trajectories are recorded at 4 different times. Lagrange velocity and acceleration were calculated and their probability density functions are analyzed in the counter flow. Changing the heater power, the counter flow pattern varies, and their statistical properties are studied.

An universal relation between the friction factor and velocity profile in a pipe flow at high Reynolds number was studied. The most important feature of this experiment is to obtain a flow rate with high accuracy using high Reynolds number actual flow facility. The high accurate flow rate measurement brings a high accurate friction velocity and Reynolds number. The velocity profile was measured using LDV and the measurement results was validated in detail. Especially, we indicated that the friction factor obtained by the direct integration of velocity profile and measurement friction factor by the pressure drop agrees very well. Based on this result, Karman constant which is the inclination in log-law velocity profile, is estimated to be 0.384. This value is nice agreement with the other canonical flows such as boundary layer and channel flow.

The visualization system was improved and the small particle motions in the superfluid could be visualized. The particle sizes are order of 1 micro meter. The boundary between particle and background was clearly distinguished and then the Lagrange trajectory of small particle was identified by image processing system. Based on these improvements of experimental procedure, the Lagrange particle trajectories are visualized and their statistical statistics are analyzed. The power-law exponent of velocity structure functions, which is equivalent to Lagrange spectral exponent, was derived. It was found that there are two different slope regions. The small scale is affected by the quantum vortex and large scale shows the uniform motion. The probability density function of Lagrange velocity and acceleration indicates that they are strongly dependent on the particle sizes and the ratio of super fluid density.

The objective of this research project was to study the dynamics and singularity of flow structures such as vortices and waves in turbulence using a large scale computer simulations. We placed astrophysical- and geophysical turbulence as the main research target because the anisotropy of flow structures plays the essential role in them. As the major achievements of the project, we can raise (1) clarification of the mechanism of development of the energy spectrum for stably stratified turbulence, and (2) understanding of singularity and characteristic geometrical features in the vortex reconnection process. In particular, it is realized that the second result is largely related to the problem of regularity of the Navier-Stokes equations, one of the seven millennium problems by the Clay Mathematical Institute.
