Abstract

The invention discloses a test bench and a method for testing visualization performance of a gas-liquid two-phase flow field, and relates to the technical field of visualization testing of a fluid flow field. The test bench comprises an acrylic test tube, a gas-phase branch, a liquid-phase branch, a mixed-phase loop and a PIV test system; an inlet end of the acrylic test tube is connected with theliquid-phase branch, an outlet end is connected with the mixed-phase loop, and the gas-phase branch is connected with the bottom of the side surface of the acrylic test tube; the PIV test system is arranged on the side surface of the acrylic test tube. The visualization of the gas-liquid two-phase flow field can be realized, and the test bench is simple in structure, convenient to operate and high in measuring precision.

Description

technical field [0001] The invention relates to the technical field of fluid flow field visualization testing, in particular to a gas-liquid two-phase flow field visualization performance test bench and testing method. Background technique [0002] Gas-liquid two-phase flow systems widely exist in various industrial systems and are closely related to human production and life. Through flow field visualization, the properties of fluid velocity and trajectory can be directly obtained, which is an important part of the research field of gas-liquid two-phase flow, and has important academic significance and practical value. [0003] At present, the existing flow field visualization test benches in this research field have complex structures, cumbersome operations, low test accuracy, and low utilization of test materials; The time is long, the work efficiency is low, and a lot of manpower, material resources and financial resources are wasted. Contents of the invention [000...
