Problems solved by technology

However, due to the large size of most closed circulating water tunnels, the volume of required liquid (i.e. liquid working medium) is large, which is very inconvenient to use; and the circulation pump is used to transport normal temperature water in the pipeline, when it is necessary to study different liquid working fluids When cavitation occurs under conditions such as quality and temperature, it is difficult for the circulating pump

Description

technical field [0001] The invention relates to the field of cavitation experiment equipment, in particular to a convenient and easy-to-use multi-working-condition temperature-controllable cavitation visualization experiment device and an experiment method. Background technique [0002] As we all know, cavitation is a phenomenon in which the partial pressure of a liquid is lower than its saturated vapor pressure. [0003] In the laboratory, it is necessary to study different types of cavitation phenomena under different working conditions (liquid working fluid, temperature, etc.) in order to further understand its characteristics. However, specific experimental setups are required to generate different types of cavitation phenomena in experimental studies. [0004] At present, the existing experimental devices are usually closed circulation water tunnels, and most closed circulation water tunnels are designed with normal temperature water as the working medium, thus produci...
