Multifunctional pressure oscillation tube test platform with two open ends

Abstract

The utility model relates to a test platform of a multifunctional pressure oscillating tube with openings at both ends, which belongs to the technical field of high and low pressure gas pressure exchange and cold and heat separation. The test platform provides a multifunctional pressure oscillation tube test platform with both ends openings that takes into account the influence between the tubes, the flow field can be measured, the diameter and length of the tube can be adjusted, the tube shape can be changed, and it can be used for actual gas research. Its main body is composed of four parts: a shell, a central shaft, a cavity turntable, and a pressure oscillation tube with openings at both ends. It can meet the flow field test needs under different pipe diameters, pipe lengths, pipe shapes and multi-pipe requirements, provide accurate data for related mechanism research, provide basis for optimizing related structures and improving the performance of air wave machines, reduce research costs, shorten Research cycle; it can be used for experimental research with natural gas as the medium, and provide more accurate experimental data for the design and optimization of gas wave machines for natural gas exploitation, gathering and transportation. The platform is simple in structure and easy to operate, and can be used not only for experimental research, but also for small-scale refrigeration and pressurization occasions.

Description

technical field [0001] The invention relates to a multi-functional test platform for a pressure oscillation tube with openings at both ends, which belongs to the technical field of high and low pressure gas pressure exchange and cold and heat separation. Background technique [0002] Gas wave technology is a kind of energy exchange between high and low pressure gases by using the wave system movement in the pressure oscillation tube, so as to achieve the purpose of refrigeration, pressurization or ejection. After decades of development, the gas wave technology has developed from the initial static gas wave refrigerator to the current pressure exchange gas wave refrigerator through the rotary gas wave refrigerator. The working core of the air wave machine is the pressure oscillation tube with openings at both ends, the rotating hub composed of a cluster of pressure oscillation tubes arranged in a circumferential direction is the rotating part of the air wave machine, and the ...

Problems solved by technology

Therefore, it is necessary to conduct detailed measurement and analysis of many flow field parameters such as wave system movement, temperature change, and condensate droplet distribution in the tube. field to measure

The patent "a single-tube gas wave refrigerator and its refrigeration method" (CN1818510A) first proposed a single-tube experimental platform for a rotary gas wave refrigerator, but its core component is a pressure oscillation tube with one end open and the other closed. The tube type is completely different from the working process of the pressure oscillating tube with openings at both ends, and it is impossible to measure important content in the flow field of the pressure oscillating tube with openings at both ends

The patent "A Simplified Internal Combustion Wave Rotor Experimental Device Based on Relative Motion" (CN104458269A) is an attempt to make the open tube at both ends stationary and the nozzle rotate, but this patent does not consider the influence between adjacent oscil
