Abstract

The invention relates to an outlet in-phase control and frequency decoupling oscillator. The outlet in-phase control and frequency decoupling oscillator comprises a mother board and a daughter board, wherein a pulse oscillator is arranged in the mother board, a plurality of first control ports are sequentially arranged in a first mother channel of the pulse oscillator, and a plurality of second control ports are sequentially arranged in a second mother channel of the pulse oscillator; and a plurality of sub-layer units are arranged in the daughter board, each sub-layer unit comprises a first sub-flow channel, a second sub-flow channel and a jet flow outlet, the output ends of the first sub-flow channels and the output ends of the second sub-flow channels are connected to the input ends of the jet flow outlets, the output ends of the first sub-flow channels and the output ends of the second sub-flow channels are arranged in a crossed mode, the angles of the output ends of the first sub-flow channels of all the sub-layer units are consistent, similarly, the angles of the output ends of the second sub-flow channels are consistent, the input ends of the first sub-flow channels of all the sub-layer units are connected to the first control ports respectively, and the input ends of the second sub-flow channels are connected to the second control ports respectively. Compared with the prior art, the outlet in-phase control and frequency decoupling oscillator has the advantages of outlet in-phase control, adjustable frequency and the like.

Description

technical field [0001] The invention relates to the field of fluid oscillators, in particular to an outlet in-phase control and frequency decoupling oscillator. Background technique [0002] The existing fluid oscillator is a device that can generate continuous oscillating jets at the outlet without mechanical moving parts. Its basic principle is: when fluid of a certain pressure enters the mixing chamber of the fluid oscillator from the inlet, Due to the Coanda effect, the main flow will inevitably adhere to the wall on one side and continue to flow along the wall. When the fluid flows through the outlet throat and flows out from the outlet, a part of the fluid will flow back to the root of the main flow along the feedback channel, prompting the main flow to turn over. Attached to the wall on the other side, the jet outlet will be flipped to the other side at the same time to produce an oscillating effect, and so on, forming a continuous oscillating effect. This device has...
