→ skos:note → "Several weak homogeneous flows can also be used to achieve a
local concentration of flow, which are stacked in the operational zone. For
flows having a wave nature, the phenomenon of interference can be used.
Since the gain in total power is not achieved in this way, it is usually
done in cases where several weak flows are easier to provide than one strong
flow."@en

flows that add up at the right place."@en
→ skos:example → "Drying paper. Wet paper is rewound from reel to reel and the
free water is squeezed out with a special roller.<br/> In order to reduce
the viscosity of the water and therefore increase the squeezing efficiency,
the paper is heated. To do this, the support drum is heated from the inside
by steam. However, it was found that the contact time between the paper and
the hot drum surface was so short that the water did not have time to heat
up due to the high winding speed. If you increase the temperature of the
drum, the surface layers adjacent to the drum will start to burn due to the
limited thermal conductivity of the paper. In other words, there is a
situation where a strong heat flow cannot be used and a weak heat flow is
not enough. Therefore, in line with the trend, a second heat flow was
introduced -- blowing hot air onto the paper from outside."@en, "The multi-oar boat. Each rower individually cannot create a
