Abstract:
1. Device ( 100 ) for mixing the components of a mass flow flowing through it, in which the components may in particular be in solid, liquid or gas form, by means of a hydrodynamic supercavitation field, in order to generate a mixture, in particular an emulsion or suspension, having a housing ( 1 ), which has an entry opening ( 2 ) for supplying at least part of the mass flow which is to be mixed and an exit opening ( 3 ), for removing the mass flow; the housing ( 1 ) having a through-flow chamber ( 4 ) with a body ( 8 ), which it is difficult for medium to flow around, arranged therein by means of a holder ( 6 ), and the body ( 8 ) which it is difficult for medium to flow around having at least two subregions ( 80 ; 10 ) which it is difficult for medium to flow around and which are each responsible for local constriction of the flow, characterized in that the through-flow chamber ( 4 ), at its start, has a through-flow chamber section ( 42 ) which narrows in the direction of flow, and in that the internal diameter of the through-flow chamber ( 4 ), following the narrowing through-flow chamber section ( 42 ), at least in the region which surrounds the body ( 8 ) which it is difficult for medium to flow around, increases in the direction of flow of the mass flow flowing through the through-flow chamber ( 4 ), wherein the body ( 8 ) which it is difficult for medium to flow around can be displaced along the direction of the center axis of the through-flow chamber ( 4 ), the subregions ( 80 : 10 ), which it is difficult for medium to flow around, of the body ( 8 ) which it is difficult for medium to flow around are produced by means of a plurality of part-bodies ( 10 ) which it is difficult for medium to flow around, and at least one of the part-bodies ( 10 ) can be displaced, independently of all the others ( 10 ), along the direction of the center axis of the through-flow chamber ( 4 ).
