Abstract

The invention provides a hydraulic jet oscillator element, which relates to the field of oscillators and includes a cover plate, a base plate and a side wall. The cover plate, the base plate and the side wall form a cavity, and a jet member is arranged in the cavity and separates the cavity into oscillations. The cavity, the vortex cavity and the output channel, the oscillating cavity and the vortex cavity are communicated through the output channel, the jet member is provided with a semi-closed groove for fluid flow, the oscillating cavity is facing the opening direction of the semi-closed groove, and the vortex cavity is facing away from the opening of the semi-closed groove The inflow hole is arranged on the cover plate, and the inflow hole communicates with the semi-closed groove; the first outflow hole is arranged on the cover plate and / or the base plate, and the first outflow hole communicates with the vortex cavity. The mechanism, only relying on the internal fluid channel setting, can self-excite to generate periodic fluid oscillation; without any movable parts, it is easy to manufacture and durable; compared with other types of fluidic oscillators, the oscillation amplitude is increased, and the frequency is easy to regulation.

Description

technical field [0001] The invention relates to the field of oscillators, in particular to a hydraulic jet oscillator element. Background technique [0002] A fluidic oscillator is a device that does not require mechanical moving parts, but only generates a continuously oscillating jet through fluid interaction. It has excellent scalability and integratability, a large bandwidth from a few Hz to tens of thousands of Hz, robustness to operate in harsh environments, and its inherent oscillatory characteristics. In recent decades, jet oscillators have achieved widespread success in issues such as flow control, separation control, downhole cleaning, downhole oscillation, and jet impingement. [0003] The existing jet oscillation device mainly adopts the principle of Coanda. Based on the Coanda effect, when a certain pressure of fluid enters the mixing chamber of the jet vibrator from the inlet, the main flow will selectively adhere to one side of the wall, so as to follow the w...
