Fig. 7 a-b shows multiple optional embodiments of rotor 12 and stator 30. At Fig. 7 aIn, " stator " 30 also rotates; In this case, excited frequency will depend on rotor 12 HesThe speed that relatively rotates between stator 30. In Fig. 7 b, one in rotor 12 and stator 30Individual, do not allow injection material pass through this device and (in Fig. 7 b, only have rotor to pass through one and inject materialMaterial); Do not allow this device that injection material passes through there is the cavity 58 that replaces through hole 22, produceTurbulent flow. Cavity 58 is made to be similar to is not with the perforate 26 of aperture 24 together.

In Fig. 7 c, aperture 24 quilts of that injection material passes through, rotor 12 or stator 30Be arranged near perforate 26, instead of as embodiment above, be located in perforate 26.Should be noted that, the main purpose of perforate 26 is to disturb along rotor 12 and stator 30 surfaces, the laminar flow of material of main part. The compression of material of main part and thin (decompression) cause microcavities, micro-Hole provides the high diffusion being caused by this device. In the process of decompression, at material of main partThe empty whirlpool of middle formation (cavitation bubbles). Cavitation bubbles grow up and the contention effect that applies in excited frequency underShrink (or blast). In the time that material of main part flows through passage 32, cavitation bubbles blast produce power,This energy contributes to injection material to be highly diffused in material of main part. Therefore, as long as inject materialMaterial and material of main part mixing reach a bit, and wherein hole occurs with the shock wave causing, onThe diffusion that face is described will produce.

As noted above, perforate 26 is for surface disturbance, itHinder the laminar flow of material of main part along passage 32 walls. In Fig. 7 e, a projection, for exampleProjection 62 can replace perforate 26 or cooperate and form a surface disturbance with perforate 26.Can also use the shape outside circle. As shown in Fig. 7 f, can be at rotor 12 and/or stator 30Middle formation groove (or projection) 64, to produce hole and shock wave.

As noted above, not all purposes all needs to generate a CFUnder shock wave, or therefrom obtain beneficial effect. Therefore, rotor 12 and stator 30 can be establishedPut multiple perforate 26 (or other tables that can occur white noise instead of some CFsFace disturbs). The structure that is used for forming hole does not need unification; On rotor 12 and stator 30Form an abundant coarse surface and also will cause hole. In addition, as shown in Fig. 7 g, do not needTo on the surface of rotor 12 and stator 30, all form hole; But, in most of the cases,If all used on two surfaces, the operation of device 10 will be more effective.

Fig. 7 h shows an embodiment, and the movement that wherein causes hole is by material of main part (alsoCan select the injection material of being pulled into) provide, instead of relative by rotor 12 and stator 30Motion provides. In the embodiment of Fig. 7 h, shape between two mutually static walls 66Become passage 32, one or two walls have towards the surface disturbance of passage 32. With onePump or other device make material of main part under high speed, be driven through this passage, to form at a high speedStream. By aperture 24 or by material of main part and injection material are mixed outward at passage, by oneIndividual or multiple injection materials are injected in passage. The relative wall 66 of material of main part draws at a high speedPlay above-mentioned microcavities and exciting.

As an example, one or more walls 66 can be fine mesh, injection materialFlow in the material of main part in passage 32 and with it and mix by this mesh. When material of main part highWhen speed flows through this mesh, the surface disturbance in mesh will cause microcavities and exciting. Excited frequencyThe closeness of mesh and the speed of material of main part will be depended on. Equally, at microcavities place, injectMaterial will be diffused in material of main part on molecular level.
