Distribution of mean flow and turbulence statistics in plunge pools

When the capacity of the spillway of a dam is exceeded for a given flood, overtopping occurs; in such cases potentially dangerous hydrodynamic actions and scour downstream of the dam need to be foreseen. Detailed studies of jets impinging in plunge pools from overflow nappe flows are scarce. This work addresses plunge pool flows, and compares numerical results against our own experiments. The ...

Surface flows from images: ten days of observations from the Tiber River gauge-cam station

Fully remote surface flow measurements are crucial for flow monitoring during floods and in difficult-to-access areas. Recently, optics-based surface flow monitoring has been enabled through a ...

Six-Jet Atomizer

The Six-Jet Atomizer 9306 is used to generate a polydisperse aerosol in high concentrations for use as seed particles for PIV and LDV measurements. The system has a built-in pressure regulator and pressure gauge, as well as a self-contained dilution system. External controls allow one through six particle-generating atomizer jets to be selected, each producing particle concentrations greater than ...
