ABSTRACT:
Each immersed jet creates turbulences as a result of the resistance of the medium in which it is immersed and at the end of its effective range the complete introduced energy is broken down into turbulent flows. These turbulent flows observed as a whole are local, thus are small-scale. However, these small-scale turbulences which have a strong eroding effect. The present invention produces as high a number as possible of small-scale turbulences and distributes them over a large volume. Large volume is to be understood as, for example, 3000–4000 m3on a surface of 2000 m2and a height of 2 m as is the case with a storage tank of 50 m diameter and a liquid column of 3 m. The problem thus lies in the optimal distribution of the introduced or applied energy.
