    The particulate jet generated by solid particles falling from a circular orifice into an unbounded quiescent air is simulated. The three-dimensional vortex method, proposed for the analysis of particle-laden free turbulent flow in a prior study, is employed for the simulation. It is found that the falling particles induce complicated three-dimensional unsteady air flow involving large-scale eddies.
    The air takes its maximum velocity at the jet centerline,
    and the velocity profile satisfies the self-similarity around the centerline. The effect of particle diameter on the velocity distribution for the two phases is ivestigated. The entrained air flow rate is favorably compared with the value predicted by the analytical models.

    <p>The characteristics of a fine-bubble plume passing through two tandem cylinders are investigated. Fine-bubbles with a mean diameter of 0.055 mm are released by water electrolysis from electrodes placed at the bottom of a tank. They induce an upward water flow around them with rising due to buoyancy. Orthogonally to the axis of such fine–bubble plume, two cylinders with a diameter <i>D</i> of 30 mm are arranged in tandem. The distance between the cylinders, <i>L</i>, ranges between 1.5<i>D</i> and 3<i>D</i>. This study visualizes the bubbles and water flow around the cylinders. It also measures the bubble velocity distribution. The experiments reveal the water and bubble shear layers originating at the sides of the lower cylinder and make clear their behavior around the upper cylinder. This study elucidates the effects of <i>L</i> on the characteristics of the fine-bubble plume, such as the stagnant bubbly flow and the bubbly wake around the cylinders.</p>

    <p>The flow and performance of a rotor of a Savonius hydraulic turbine provided with a shield plate were analyzed by the two-dimensional simulations. The rotor diameter <i>D<sub>R</sub></i> is 142 mm, and the Reynolds number based on the velocity of the main flow <i>U</i><sub>0</sub>, <i>U</i><sub>0</sub><i>D<sub>R</sub></i>/<i>ν</i>, is 1.1×10<sup>5</sup>. The shield plate with a length of 0.5<i>D<sub>R</sub></i> is installed upstream of the rotor, perpendicular to the main flow. The comparative experimental studies have visualized the flow and clarified that the shield plate increases the power output of the rotor. The vortex in cell method combined with the volume penalization method was applied to the flow simulation, and the torque acting on the rotor was computed with a custom method by the authors. The simulated flows around the shield plate and rotor agreed with the experimentally visualized ones. The simulation successfully revealed the effect of the shield plate on the flow and power output of the rotor. These demonstrate the applicability of the present simulation method for the performance prediction of the rotor of Savonius hydraulic turbines provided with a shield plate.</p>

    <p>To investigate the variation in a sphere's motion and the behavior of the air-water interface induced by the sphere, a solid sphere is launched vertically upward in water toward the air-water interface. Four spheres with different densities <i>ρ<sub>p</sub></i> were studied: a stainless steel sphere (<i>ρ<sub>p</sub></i> = 7930 kg/m<sup>3</sup>), an alumina sphere (<i>ρ<sub>p</sub></i> = 3900 kg/m<sup>3</sup>), a Teflon sphere (<i>ρ<sub>p</sub></i> = 2180 kg/m<sup>3</sup>), and a Duracon sphere (<i>ρ<sub>p</sub></i> = 1360 kg/m<sup>3</sup>). By experimentally visualizing the sphere motion in water, their launch velocity can be set with high accuracy. When a sphere passes through the air--water interface, it makes the interface more complex and entrains water. Additionally, spheres with a small value of <i>ρ<sub>p</sub></i> were demonstrated to not always vertically collide with the air--water interface.</p>

    <p>This study investigates the flow past two cylinders arranged in tandem within a microbubble plume inside a tank. Microbubbles with a mean diameter of 0.055 mm are released by water electrolysis from electrodes placed at the bottom of the tank. Upon rising, these microbubbles induce an upward water flow around them due to buoyancy. Orthogonally to the axis of this microbubble plume, two cylinders with a diameter <i>D</i> of 30 mm are arranged in tandem. The distance between the cylinders, <i>L</i>, ranges between 1.5<i>D</i> and 3<i>D</i>. The bubbles and the water flow around the cylinders are visualized, and the bubble velocity distribution is measured. The experiments reveal the water and bubble shear layers originating at the sides of the lower cylinder, and allow the elucidation of their behavior around the upper cylinder. Furthermore, this study makes clear the effects of <i>L</i> on the flow around the two cylinders, such as the stagnant bubbly flow and the bubbly wake.</p>

    <p>This study is concerned with the numerical simulations of the flow and performance of a rotor of a hydraulic Savonius turbine. The flow was simulated using the vortex in cell (VIC) method in combination with the volume penalization (VP) method. The torque acting on the rotor was computed using a custom method, which can accurately calculate the fluid forces on solid bodies in flows simulated by the VIC-VP method, to analyze the rotational speed and power output of the rotor. The simulated flow around the rotating blades agreed qualitatively with the experimentally visualized flow, and the analyzed relation between the rotor's rotational speed and power output agreed well with the experimentally measured relation. These demonstrate that the VIC-VP method in combined with the authors' method for calculating fluid forces is applicable for the simulations of flow and performance of hydraulic Savonius turbines.</p>

    <p>Pin-on-disk sliding tests have been carried out to investigate lubrication properties of nanometer-thick liquid films. However, it is difficult to experimentally observe the detailed flow behavior of the films at the nanoscale contacting interface. To solve this problem, we performed numerical simulations with the moving particle semi-implicit (MPS) method in this study. To model a pin sitting on a rotating disk lubricated with a nanometer-thick liquid film, the effects of surface tension and external force were taken into account in the governing equation. As a result, details of the behavior of the film and pin and their interference were visualized. This result suggests that the MPS method is potentially useful for clarifying the mechanism of lubrication with nanometer-thick liquid films.</p>

    <p>This study conducts experimental exploration on the motion of a solid spherical particle falling in a microbubble plume and the bubble behavior around the particle. Bubbles with a mean diameter of 0.037 mm, released into a rectangular conduit using the electrolysis of water, rise by the buoyant force and induce a bubble plume. A spherical particle with a diameter 11.1 mm and density 1130 kg/m<sup>3</sup> is released from the top of the conduit. The experiment clarifies that the particle falls meandering through the plume and that the terminal velocity is almost the same as that for a particle falling in quiescent water. The experiment also makes clear that the bubbles separate from the particle surface and that the separation induces a stagnation area just behind the particle. A wake still exists at a location with a distance of three times of the particle diameter from the particle.</p>

    <p>In the present study, we propose a method for calculating the fluid dynamic forces acting on bodies in a two-dimensional simulation of a flow around a moving body by using the vortex–in–cell method. The body is represented using the volume penalization method which introduces the influence of the body on the flow as an external force in the form of a penalization term into the Navier–Stokes equation. The pressure field is computed by solving the Poisson equation, which is derived by obtaining the divergence of the Navier-Stokes equation. The pressure and viscous stress on the body surface are obtained from a quadratic function along the vector normal to the surface. A flow around a circular cylinder oscillating in still water is simulated, and the fluid dynamic force acting on the cylinder is calculated using the proposed method. The velocity profiles across four cross-sections at three different time points agree well with the results of a measurement conducted using a laser Doppler velocimeter. The in-line force acting on the cylinder agrees with the results of the simulations performed using the boundary-conforming formulation.</p>

    <p>This study simulates the behavior of a vortex ring launched toward the interface of a two-layer density stratified fluid and the resulting mixing phenomena between the fluids. Initially, the density-stratified fluid is in a static condition in a tank. The upper and lower fluids are glycerol aqueous solution and an aqueous solution of potassium dihydrogen phosphate, respectively. The vortex ring with a diameter of 26.4 mm is launched vertically downward from the upper fluid region. It travels by the vertical motion toward the density interface. The Reynolds number, based on the circulation of the vortex ring, is 3500. The simulation conditions are parallel with an experimental work of one of the authors. The vortex in cell method, which was presented by the authors for flow simulations of two-layer density stratified fluid in a prior study, is used. The simulation favorably highlights the collision, deformation and penetration of the vortex ring at the density interface. It also successfully reveals the mixing between the upper and lower fluids induced by the motion of the vortex ring. These simulated results are discussed by comparing with the corresponding experimental ones.</p>

    This study explores the bubble plume around a circular cylinder in a water tank. Small gas bubbles with diameter of less than 0.06 mm are released from electrodes on the bottom of the tank by using the electrolysis of water. They induce the water flow with rising by the buoyant force. In such bubble plume, a circular cylinder with diameter D of 30 mm is mounted at an elevation of 6.5D above the electrodes. This study visualizes the bubbles and water flow around the cylinder and measures the bubble velocity distribution. The experiment elucidates the separated shear layers originating from the cylinder wall, their roll-up, and the bubble entrainment in the resultant large-scale eddies behind the cylinder.

    This study is concerned with the development of a hollow micro-hydraulic turbine excellent in foreign matter passage performance. The runner has a circular hollow around the central (rotating) axis so that foreign matter included in water can easily flow without blocking the turbine. The laboratory experiments are conducted to investigate the turbine performance. Though the turbine efficiency decreases with increasing the hollow ratio e when ε>0.25, it remains unchanged when ε&le;0.25. The hollow of the runner effectively heightens the passage performance of the polyester fibers entrained into the turbine. The developed micro-hydraulic turbine of ε&ge;0.375 is not blocked by the fibers and maintains its function.
