Description

technical field [0001] The invention belongs to the technical fields of low-temperature air separation and low-temperature liquefaction, and relates to an optimal design method for anti-cavitation of a two-phase low-temperature liquid expander. Background technique [0002] As a kind of hydraulic machinery, cryogenic liquid expander is similar to traditional hydraulic (or hydraulic) machinery, and cavitation inevitably occurs. The collapse of cavitation bubbles will generate extremely high local pressure, which will cause a great impact on the surface material of the structure, resulting in cavitation corrosion damage; it will also induce unit vibration, threatening the stable operation of the liquid expander and even the low temperature system. Therefore, the effective suppression of the vortex cavitation flow in cryogenic liquid expanders is of great significance. [0003] Cavitation phenomenon refers to the phenomenon that the partial pressure of the liquid is lower than...
