Abstract
Cavitation reactor for hydrodynamic generation of homogeneous, oscillating cavitation bubbles in a fluid, including, while forming a flow duct and arranged one behind the other in the direction of flow of the fluid, an acceleration section designed to increase a flow velocity, a diaphragm arranged transversely to the direction of flow with a plurality of micro-passages designed for generating cavitation bubbles, where at least 10 micro-passages per cm2 are provided over an entire flow cross-sectional surface defined on an oncoming flow side of the diaphragm, a stabilization section designed for stabilizing an oscillation of cavitation bubbles, and a collapse section with at least one widening of a flow cross-sectional surface of the flow duct in the direction of flow.
Claims24
A cavitation reactor for hydrodynamic generation of substantially homogeneous, oscillating cavitation bubbles, comprising a flow duct that includes
- an acceleration section configured to increase a flow velocity of a flow of a fluid,
- a diaphragm arranged proximate the acceleration section in the direction of the flow and transversely to the direction of the flow, the diaphragm having a plurality of micro-passages configured to generate cavitation bubbles, wherein at least 10 micro-passages per cm2 are provided over an entire flow cross-sectional surface defined on an oncoming flow side of the diaphragm,
- a stabilization section that is arranged proximate the diaphragm in the direction of the flow and configured to stabilize an oscillation of cavitation bubbles, and
- a collapse section that is arranged proximate the stabilization section in the direction of the flow and has at least one widening of a flow cross-sectional surface of the flow duct in the direction of the flow.

A method for hydrodynamic generation of substantially homogeneous, oscillating cavitation bubbles in a fluid, comprising the following steps:
- accelerating the fluid,
- flowing the fluid onto a diaphragm having a plurality of micro-passages, wherein at least 10 micro-passages per cm2 are formed over an entire flow cross-sectional surface defined on an oncoming flow side of the diaphragm,
- flowing the fluid through the micro-passages to generate the fluid into cavitation bubbles,
- stabilizing an oscillation of the cavitation bubbles, and
- widening of the flow of the fluid in the direction of the flow in order to collapse the cavitation bubbles.
