- the filling rate of the liquid in the transfer pipe 10 is, for example, 10% or more and 90% or less. Therefore, a layer of liquid and air exists in the transfer pipe 10.

- a vortex street with an axis of rotation perpendicular to the extension direction of the transfer piping 10 was generated in the water inside the transfer piping 10.
- the reference symbol A1 is used to indicate the rotation of each vortex in the vortex street. Adjacent vortices in the vortex street rotate in opposite directions to each other, and mixing was achieved by the vortex street. In other words, by experimentally confirming the generation of a vortex street, it was confirmed that the device and method function as a mixing device.

- the generation of vortex rows was confirmed even when the filling rate was 10% (minimum value) and 90% (maximum value).
- the symbols A5 and A6 are attached to indicate the rotation of each vortex in the vortex row. Therefore, from these results, it was confirmed that the stirring and transporting device 1 and the stirring and transporting method of this embodiment are effective when the filling rate is in the range of 10% to 90%. Therefore, by specifying the filling rate in this manner, it is possible to realize stable generation of vortex rows and stable stirring.
- Figure 9 shows the results of a numerical simulation when the filling rate is 60% and the Reynolds number Re is 100.
- the Reynolds number Re was adjusted by changing the viscosity ⁇ of the liquid.
- the reference symbol A4 is used to indicate the rotation of each vortex in the vortex street.
- Table 1 shows the results of a summary of the minimum Reynolds number Re at which the occurrence of a vortex street could be confirmed for each filling rate.
- the stirring and transporting device 1 and stirring and transporting method of this embodiment may be effective when the Reynolds number Re is 98 or more (when the filling rate is 60%). Specifically, it was confirmed that by specifying the Reynolds number Re in this way, it may be possible to generate vortex streets, and stable stirring may be achieved. Therefore, the Reynolds number Re may be set to 98 or more. Furthermore, the Reynolds number Re may be set to 326 or more so that vortex streets are generated stably at a total filling rate of 10% to 90%. Furthermore, the Reynolds number Re may be appropriately set to a value equal to or greater than the minimum value shown in Table 1 depending on the filling rate to be set.
- Figure 10 shows the results of a numerical simulation when the length of the transfer piping 10 is 0.6 times its diameter. As a result, the occurrence of vortex streets was confirmed even when the length of the transfer piping 10 was 0.6 times its diameter (i.e., the aspect ratio was 0.6).
- the reference symbol A7 is used to indicate the rotation of each vortex in the vortex street.
- Such simulations were performed with various changes to the Reynolds number Re and filling rate to confirm the occurrence of vortex streets.
- Table 2 below shows the results of a summary of the minimum aspect ratios at which the occurrence of vortex streets could be confirmed, for each filling rate and the minimum Reynolds number for that filling rate (see Table 1 above).
- the stirring and transporting device 1 and the stirring and transporting method of this embodiment may be effective (when the filling rate is 10%) when the length of the transport pipe 10 is 0.6 times or more the diameter (aspect ratio is 0.6 or more). Therefore, by specifically specifying the ratio of the length and diameter (aspect ratio) of the transport pipe 10 in this way, it may be possible to realize stable generation of vortex streets, and stable stirring may be realized. Therefore, the transport pipe 10 may have a length of 0.6 times or more the diameter of the circle of the cross section perpendicular to the stretching direction (i.e., an aspect ratio of 0.6 or more).
- the transport pipe 10 may have a length of 1.8 times or more the diameter of the circle of the cross section perpendicular to the stretching direction (i.e., an aspect ratio of 1.8 or more).
- an aspect ratio equal to or greater than the minimum value shown in Table 2 may be appropriately set according to the filling rate to be set.
- Figure 11 is a graph of the results of a numerical simulation showing the relationship between the strength of the circulating flow (vortex flow) and the ratio K1 (average flow velocity/inner wall surface velocity). Note that in the numerical simulation of Figure 11, the Reynolds number Re for the viscosity of the liquid was set to 200, the filling rate was set to 40%, and the average flow velocity was changed in various ways.
- Fig. 12 is a graph showing the relationship between the strength of the circulating flow (vortex flow) and the ratio K1, which is a result of a numerical simulation.
- the average flow velocity was set so that the mainstream Reynolds number Re m was 150, the filling rate was set to 40%, and the Reynolds number Re was changed in various ways.
- particles contained in a liquid can also be aggregated under a predetermined condition.
- the predetermined condition may be as follows.
- the Stokes number St in stirring is 2.7 ⁇ 10 ⁇ 5 or more (St ⁇ 2.7 ⁇ 10 ⁇ 5 ) at the Reynolds number Re at which a vortex street occurs
- the ratio K2 of the terminal velocity of the free fall of the particles to the inner wall surface velocity in the rotation direction of the transport pipe 10 is ⁇ 0.01 or more and 0.52 or less ( ⁇ 0.01 ⁇ K2 ⁇ 0.52).
- the terminal velocity of the free fall of the particles here also includes the case where the particles float (the case where the terminal velocity is negative). Specifically, the ratio K2 ⁇ 0 indicates that the particles float.
- the Stokes number St is expressed by the following formula (1):
- d represents the diameter of the particle
- ⁇ represents the viscosity of the liquid
- ⁇ represents the density of the liquid
- ⁇ p represents the density of the particle
- ⁇ represents the rotation speed of the transfer pipe 10.
- the ratio K2 is expressed by the following formula (2).
- g represents the gravitational acceleration
- R represents the radius of the transfer pipe 10
- the other parameters are the same as those shown in formula (1).
- the density ⁇ p of the particles was set to 1200 [kg/m 3 ] (i.e., the density ratio of the particles to the liquid was 1.2/1.0), and the number of particles was set to about 100,000.
- the particle diameter d was changed in various ways, the time evolution of the particle field was observed, and the change in the spatial distribution of particles with respect to the particle diameter d (i.e., the Stokes number St) was confirmed.
- Figure 13 shows the initial particle placement in a numerical simulation for Stokes number St. As shown, the particles are evenly distributed in the liquid.
- the Stokes number St in stirring may be set to 2.7 x 10-5 or more (St ⁇ 2.7 x 10-5 ).
- the results of examining the ratio K2 (terminal velocity of free fall of particles/inner wall surface velocity in the rotation direction of the transfer pipe 10) will be described.
- the radius R of the transfer pipe 10 was set to 1 [cm]
- the viscosity ⁇ of the liquid was set to 0.001 [Pa ⁇ s]
- the density ⁇ of the liquid was set to 1000 [kg/m 3 ]
- the filling rate was set to 40%
- the rotation speed ⁇ of the transfer pipe 10 around the horizontal axis was set to 4 [rad/s] (94 rpm). This resulted in the Reynolds number Re being set to 400.
- the particle diameter d was set to 100 [ ⁇ m], and the number of particles was set to about 100,000. Under these conditions, the particle density ⁇ p was changed in various ways, the time development of the particle field was observed, and the change in the spatial distribution of particles relative to the particle density ⁇ p (i.e., the ratio K2) was confirmed.
- Figure 19 shows the initial particle placement in the numerical simulation for ratio K2. As shown, the particles are evenly distributed in the liquid.
- Fig. 25 is a graph showing the results of confirming the ratio of particles on the inner wall surface of the transfer piping 10 or near the liquid surface.
- Fig. 24 is a graph confirming the dependency of N ⁇ /Np on the ratio K2, where N ⁇ is the number of particles within 100 [ ⁇ m] from the inner wall surface of the transfer piping 10 or the liquid surface , and Np is the total number of particles.
- the ratio K2 is -0.01 or more and 0.52 or less (-0.01 ⁇ K2 ⁇ 0.52), and N ⁇ /N p is equal to or less than the threshold value of 0.4. In other words, it was confirmed that in this range, 60% or more of the particles are not located near the inner wall surface or the liquid surface, but are densely located in the central region of the liquid. Therefore, the ratio K2 may be set to -0.01 or more and 0.52 or less (-0.01 ⁇ K2 ⁇ 0.52).
- the shape of the transfer pipe 10 is not limited to a circular pipe, but may be a pipe of any shape with a smooth inner surface. Therefore, the shape of the cross section perpendicular to the extension direction of the transfer pipe 10 may be circular as in the above embodiment, or may be a shape other than circular.
- the shape of the cross section perpendicular to the extension direction of the transfer pipe 10 may be elliptical or donut-shaped.
- the thickness (diameter) of the transfer pipe 10 does not have to be uniform, that is, it may change depending on the position in the extension direction.
- the transfer pipe 10 may have a tapered shape that becomes thinner from one end to the other end.
- the transfer pipe 10 need not only be arranged horizontally, but also need only be arranged approximately horizontally, and for example, a tilt of a few degrees from the horizontal direction is acceptable. Furthermore, the rotation axis RA and the central axis of the transfer pipe 10 do not need to be perfectly aligned, and may be slightly misaligned (eccentric).
- the configuration of the rotation mechanism 20 can be variously considered other than the above embodiment, and any configuration that can rotate the transfer pipe 10 around the rotation axis RA can be adopted.
