Method and apparatus for space letting at overflowed up or output faces forming eddies

A method for space Let of vortices that form at overflowed up or output surfaces by rolling of separated flows, wherein thermal energy is so introduced into the flow, that it passes into the region of the vortex, characterized in that the thermal energy by means of a gas - dust or mist-like carrier material (17) is introduced, which is injected in the region of the vortex axis (9) of the vertebra (7) in the flow (15) and that an exothermic reaction of the support material (17) in the flow (15) is triggered.
