The minimum cross section of the stream occurs downstream of the actual necking, called reduced flow cross section. Condensing flow cross section at the maximum flow rate, the flow rate is increased along with the reduced flow cross section of the pressure is greatly reduced. When the stream of expanding into a larger area, the speed drops, the pressure increases, but the downstream pressure will not fully recover to the upstream pressure, which is larger as a result of internal turbulence and energy consumption. If the contraction flow pressure drops liquid pvc section at the corresponding saturated vapor pressure pv temperature below the stream of steam and gas had dissolved in the water to escape, forming small steam mixed with the gas bubble, the lower the pressure, The more bubbles. If the pressure p2 downstream of the orifice remains below the saturation vapor pressure of the liquid, the bubble will continue to produce in the downstream piping, liquid and vapor phases are mixed, and this phenomenon is flashing. If the downstream pressure was returned to the saturated vapor pressure above the liquid, bubble under the action of high pressure, rapid condensation and rupture, rupture of bubbles at the moment, generating a partial hole, high pressure water flows at high speed the original bubble possession of the space, forming a shock. Since the bubble of gas and steam all dissolved in an instant too late and condensation under the impact force is divided into small bubbles, and then be compressed high-pressure water, condensation, thus forming repeatedly, and produce a similar to what we can imagine sand flowing through the pipeline noise, this phenomenon is called cavitation. Channel material surface at a water hammer pressure to form fatigue was severely damaged. We put the formation of bubbles, development and rupture the material damage that the whole process is called cavitation.
