It is important to understand in which circumstances the suspension of particles leads to significant velocity enhancements in turbulent flows. Assuming the validity of the Kolmogorov-Barenblatt model for turbulent flows loaded by small particles, we show that this occurs in the regime of limiting saturation, when the flow suspends as many particles as the given external conditions allow. In addition we consider the consequences of the presence of arbitrarily small particles. We discuss in detail the application of the model to suspended droplets in hurricanes above the ocean.

Abstract
It is important to understand in which circumstances the suspension of particles leads to significant velocity enhancements in turbulent flows. Assuming the validity of the Kolmogorov-Barenblatt model for turbulent flows loaded by small particles, we show that this occurs in the regime of limiting saturation, when the flow suspends as many particles as the given external conditions allow. In addition we consider the consequences of the presence of arbitrarily small particles. We discuss in detail the application of the model to suspended droplets in hurricanes above the ocean.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
