Embodiment approach

[0029] A typical implementation of the present invention is as follows:

[0030]The same gas source fluid separated from the main jet and equal to the total pressure of the main jet is introduced from the outside into the self-excited oscillation cavity, and self-excited oscillations are performed to generate periodic micro-jet, and the main jet is pushed from the vertical excitation port on the side of the attached wall. The way of pulling the main jet makes the main jet oscillate, thereby increasing and maintaining the total pressure. The self-exciting oscillating cavity uses a sonic oscillating jet generator as the micro-jet controller of the present invention, so that the main jet is distributed. And the change of the length of the sound wave control tube can change the switching frequency of the micro-jet attached to the wall.

[0031] Such as image 3 As shown, the self-excited micro-fluidic control multi-tube oscillator of the present invention mainly includes an osci...

Abstract

The invention belongs to the technical field of jet control engineering refrigeration of pressure gas, and relates to a self-excited microjet control multi-tube oscillator. The self-excited microjet control multi-tube oscillator is special equipment of gas jet control like a refrigeration device, a same-gas-source fluid separated from main jet and equal to the total pressure of the main jet is intruded into a self-excited oscillating cavity from the outside, self-excited oscillating is carried out to generate periodic microjet, the main jet is pushed and pressed at the wall attaching side froma perpendicular exciting opening, the manner of pushing and pulling the main jet is used for achieving main jet oscillating, the main pressure is increased and continues, continuous oscillating is finally achieved, and the problem that energy consumption is high due to self-excited jet oscillating is solved. The oscillator has the advantages of being simple in structure, convenient to operate andmaintain and the like, external power is not needed, running is stable and reliable, and the self-excited microjet control multi-tube oscillator is suitable for treating high-pressure gas media.

Description

technical field [0001] The invention belongs to the technical field of jet flow control engineering refrigeration of pressurized gas, relates to a self-excited micro-jet flow control multi-tube oscillator, and is special equipment necessary for gas jet flow control such as refrigeration machinery. Background technique [0002] Jet is a special type of fluid motion. It is related to the flow of jet in the fields of aviation industry, hydraulic engineering, medical and sanitation, and automatic control. Therefore, jet has become an important content of fluid mechanics research. The jet oscillator is based on the jet theory, on the basis of the jet oscillating element, an additional feedback channel generates fluid oscillation, and the flow measurement is realized by measuring the oscillation frequency of the fluid. The theoretical analysis of the nature and characteristics of the jet is the prerequisite for the study of the jet oscillator, which lays the foundation for the res...
