Among them, the SPH algorithm is a commonly used numerical simulation method, which disperses the continuous fluid into a series of particles, and then solves the motion equation of these particles to simulate the behavior of the fluid. This method is very effective in dealing with complex fluid dynamics problems, especially in dealing with multiphase flow and nonlinear problems.
[0003] In order to verify the effectiveness of the SPH algorithm, a related experiment machine is usually designed to simulate the dispersion mixing process of the dispersed phase droplet in three-dimensional space, and optical observation equipment is introduced for experimental observation, such as a high-speed camera.

[0027] In order to facilitate the understanding of the utility model, the utility model will be described more fully below with reference to the related drawings. The drawings show several embodiments of the utility model. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
[0028] It should be understood that when an element as a "fixed" to another element, it can be directly on another element or can exist in the middle of the element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can exist in the middle of the element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0030] Please refer to Figures 1 to 5 , the utility model provides a kind of dispersed phase droplet dispersion mixing experimental machine, including transparent barrel 100, transparent two rotors 200, drive mechanism 300.The axial dimension of barrel 100 is less than the radial dimension of barrel 100, and mixing cavity 110 is provided in barrel 100, and mixing cavity 110 includes two first chamber 111 and second chamber 112 that are interconnected, wherein, first chamber 111 and second chamber 112 are formed by two groups of two cylindrical cavities that are parallel to the axial direction of barrel 100, two rotors 200 are respectively arranged in first chamber 111 and second chamber 112, and drive mechanism 300 is drivingly connected with two rotors 200.When drive mechanism 300 is in working condition, drive mechanism 300 simultaneously drives two rotors 200 to rotate in the same direction and at the same speed, and under the shearing and stretching flow generated by the rotation of two rotors 200, dispersed phase in first chamber 111 and second chamber 112 forms dispersion mixing in experimental fluid, and since the axial dimension of barrel 100 is less than the radial dimension of barrel 100, dispersion mixing mainly occurs in the cross section perpendicular to the axial direction of barrel 100 at this time, i.e. the key position of shearing and stretching flow.
[0031] In some optional embodiments, as Figure 2 , Figure 5As shown, the front end face of the cylinder 100 is provided with an opening 113 communicating with the mixing chamber 110 and an end cap 120 covering the opening 113. To allow for direct observation of the dispersion and mixing process of the dispersed phase droplets from the end face of the cylinder 100, the end cap 120 is transparent. To prevent fluid in the mixing chamber 110 from leaking out of the opening 113, the end cap 120 and the opening 113 are fitted with a transition fit, with a gap of 0.2 mm to 0.3 mm. Furthermore, a sealing element, such as a rubber sealing ring, can be provided between the end cap 120 and the opening 113 to improve the sealing performance between them.
[0032] In some alternative embodiments, the end cap 120 is made of quartz glass, which ensures high transparency while maintaining high structural strength and a low coefficient of friction. The low coefficient of friction reduces the impact on the fluid within the mixing chamber 110, and the transparent design allows for easy and direct observation of the dispersion and mixing process of the dispersed phase droplets from the end face of the cylinder 100.
[0033] In some optional embodiments, the cylinder 100 is made of acrylic material. Acrylic material can ensure that the cylinder 100 has high transparency, so as to facilitate the direct observation of the dispersion and mixing process of the dispersed phase droplets from the axial side of the cylinder 100. It also facilitates the recording of the dispersion and mixing process of the dispersed phase droplets from the axial side of the cylinder 100 by a high-speed camera. It also facilitates cross-sectional velocimetry by a particle imaging velocimeter to obtain the velocity inside the flow field, thereby providing reliable data for subsequent analysis.
[0034] In some alternative embodiments, such as Figure 1 , Figure 2 As shown, the drive mechanism 300 includes a driver 310, a reducer 320, and a rotating shaft 330. The reducer 320 is connected to the driver 310, and the two ends of the rotating shaft 330 are connected to the reducer 320 and the rotor 200, respectively. Optionally, the reducer 320 can be a gearbox, and the driver 310 can be a rotary motor, rotary cylinder, or other power device. By adjusting the speed of the driver 310 or changing the transmission ratio between the reducer 320 and the driver 310, the speed of the rotor 200 can be adjusted, thereby changing the experimental conditions.
[0035] In this embodiment, the high-speed, low-torque driver 310 is reduced in speed by the reducer 320, so that the rotor 200 is in a low-speed, high-torque state, thereby enabling the rotor 200 to rotate stably and reliably, ensuring that the dispersed phase droplets are stably dispersed and mixed in the experimental fluid.
[0036] In some alternative embodiments, such as Figure 4As shown, a shaft hole 130 is provided on the cylinder 100, and one end of the rotating shaft 330 passes through the shaft hole 130 into the mixing chamber 110. In order to prevent the fluid in the mixing chamber 110 from leaking out of the shaft hole 130, the rotating shaft 330 and the mixing chamber 110 are sealed together.
[0037] In some alternative embodiments, such as Figure 4 As shown, the dispersion and mixing experimental machine for dispersed phase droplets also includes a skeleton seal 400, which achieves a sealing setting between the rotating shaft 330 and the mixing chamber 110. Specifically, the skeleton seal 400 is sleeved on the rotating shaft 330 and fixed on the outer wall of the cylinder 100.
[0038] In some alternative embodiments, to further improve the sealing between the rotating shaft 330 and the mixing chamber 110, such as... Figure 4 As shown, a sealing ring 500 surrounding the shaft hole 130 is sandwiched between the skeleton seal 400 and the cylinder 100. Optionally, the sealing ring 500 can be a rubber sealing ring.
[0039] In some alternative embodiments, for ease of adding the dispersed phase and experimental fluid, such as Figure 5 As shown, a filling port 140 is provided at the top of the cylinder 100. In order to prevent the external environment from affecting the fluid in the mixing chamber 110, and to prevent the fluid in the mixing chamber 110 from splashing out from the filling port 140, a plug is provided in the filling port 140. Optionally, the plug can be a silicone plug. When adding the dispersed phase and the experimental fluid, the experimental fluid or the dispersed phase can be injected into the mixing chamber 110 by penetrating the silicone plug with a syringe.
[0040] In some alternative embodiments, to facilitate the removal of the dispersed phase and experimental fluid, such as Figure 5 As shown, a vent 150 is provided at the bottom of the cylinder 100. To prevent the external environment from affecting the fluid in the mixing chamber 110, and to prevent the fluid in the mixing chamber 110 from flowing out of the vent 150, a plug is inserted into the vent 150. Optionally, the plug can be a silicone plug, which can be removed when adding the dispersed phase and experimental fluid. In this embodiment, by opening the vent 150, part of the fluid in the mixing chamber 110 can be released, thus achieving the purpose of adjusting the filling degree of the mixing chamber 110.
