DEVICE FOR INFLUENCING THE FLOW OF A FLUID MEDIUM

摘要

The aim of the disclosed device for influencing the flow of a fluid medium is to stimulate regulated hydrodynamic cavitation, for the purpose of heating the medium and/or dispersion into said medium of solid and liquid materials, for example. The device comprises an axisymmetric circulating channel for pumping over the main stream of the fluid medium, as well as an aperture in the channel wall used to admit agitating jets into the main stream and to stimulate hydrodynamic cavitation. In order to reduce hydraulic waste and noise while increasing reliability and yield, said aperture opens directly into the channel cavity, and its geometric axis intersects the geometric axis of the channel at an angle of between -60 DEG and +45 DEG . It is preferable to have several such apertures for admitting into the main stream agitating jets of a fluid of the same or of a different chemical composition.
