Vortex ring generation device based on radial disturbance principle

Abstract

The invention discloses a vortex ring generation device based on radial disturbance principle. The vortex ring generation device based on the radial disturbance principle comprises an air feed device,a radial disturbance device, a ventilating duct and two opening and closing plates, wherein the air feed device, the radial disturbance device and the two opening and closing devices are sequentiallyarranged in the ventilating duct along the air flow direction, the two opening and closing plates are transversely and symmetrically arranged in the ventilating duct, semi-circular holes symmetrically arranged are formed in the two opening and closing plates, and the radial disturbance device is connected with the two opening and closing plates, and drives the two opening and closing plates to open or close. The vortex ring generation device based on the radial disturbance principle achieves continuous air feeding, generates a plurality of vortex rings on a section of continuous airstream, connects the vortex rings through common air, greatly improves ventilation rate, and can meet the requirement for the minimum ventilation rate in the heat supply or refrigeration field.

Description

Technical field [0001] The invention relates to the technical field of fluid mechanics, in particular to a vortex ring generating device based on the principle of radial disturbance. Background technique [0002] In the existing vortex ring generating device, the vortex rings are mainly generated one by one intermittently, and the ventilation volume is greatly restricted. For heating or cooling fields with minimum ventilation volume standards, the generated vortex ring ventilation volume cannot meet the requirements. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a vortex ring generating device based on the principle of radial disturbance in response to the above-mentioned defects in the prior art, which realizes continuous and uninterrupted air supply and generates several vortex rings on a continuous airflow. And there is a common wind connection between the vortex ring and the vortex ring, which greatly increases the ...
