Research on the Feasibility Verification Based on Continuous Vortex Ring Generator and the Matching Degree of Device Parameters

Abstract

This paper proposes a new type of continuous vortex ring generator, which can significantly increase vortex ring generators’ ventilation by studying the matching degree of device parameters. This paper uses the model proposed by Gharib analysis, and the dimensionless circulation of the vortex ring measured by the vortex profile method to explore the properties of the vortex ring. In this paper, by studying the generation principle of a vortex ring in which a dynamic fluid flows through mechanical drainage and alternately ejected from a tapered spout and an annular spout, explore the best conditions for the continuous vortex ring. The research results show that a section of static fluid with a radial restriction is driven by the same dynamic fluid with a certain speed, and the fluid-carrying capacity of the vortex ring increases as the length to diameter ratio increases, after reaching a certain length no more noticeable change. An annular spout is equipped with a guide cylinder, and its clearance coefficient is within a specific reasonable range. When the annular spout ejects an airflow whose length-to-diameter ratio is in a specific functional relationship with the clearance coefficient, a high-quality vortex ring can be produced.
