Abstract

L'invention a pour objet un dispositif pour influencer l'écoulement d'un fluide, destiné à provoquer une cavitation hydrodynamique contrôlée à des fins de réchauffement du fluide et/ou de dispersion dans ledit fluide de substances solides ou liquides. Le dispositif est muni d'un canal d'écoulement axisymétrique qui sert à pomper le flux principal du fluide, ledit canal comportant un orifice servant à injecter dans le flux principal un jet d'agitation pour provoquer la cavitation hydrodynamique. Pour diminuer les pertes hydrauliques et le niveau de bruit ainsi que pour augmenter la fiabilité et le rendement du dispositif, l'orifice s'ouvre directement dans le creux du canal, son axe géométrique traversant l'axe géométrique de ce dernier sous un angle compris entre -60° et +45°. Il est préférable d'avoir plusieurs orifices de ce type pour pouvoir injecter dans le flux principal des jets d'agitation constitués d'un fluide identique ou différent du point de vue de sa composition chimique.
