Embodiment Construction
[0032] The present invention will be further described in detail below in combination with specific embodiments.
[0033] The design principle of the nozzle of the present invention is: because the characteristic of the water jet of general nozzle is as follows figure 2 The shown continuous jet, in order to enhance the impact force effect, let the water jet become image 3 The water hammer jet shown in the figure is combined with the cavitation effect. Therefore, the nozzle of the present invention adopts the principle of fluid self-excited oscillation to make the high-speed water flow in the cavity generate pulsed oscillating water flow. The principle of self-excited oscillation is to adopt a shape design similar to the shape of an organ pipe or a Helmholtz tube, and when designing the curve of the cavity wall, try to make the fluid generate a separation vortex in the boundary layer and form a hydrodynamic excitation. Therefore, when the high-speed water flow passes through...
