Turbulence

Instrumentation for profiling turbulence and vertical dynamics in the water column, ideal for mixing and transport studies.

Measuring water flows with high temporal or spatial resolution makes it possible to undertake studies of boundary layers or turbulent regimes. Typical applications include sediment transport studies, surf-zone dynamics, orbital velocity analyses and the characterisation of turbulent flows. A powerful tool for high temporal resolution measurements is the acoustic Doppler velocimeters manufactured by Nortek A/S, which measure 3D flows within a small water volume at frequencies of up to 200 Hz. Micro-scale scalar fluxes can be studied using microturbulence probes manufactured by Rockland Scientific. The combined use of Nortek’s Vector with RS’s microSquid enables a detailed description of scalar variables associated with micro-scale dynamics. These instruments allow non-intrusive measurements both in the field (Vector) and in laboratory environments (Vectrino+). If your interest lies in high spatial resolution vertical measurements, Nortek HR profilers operating at 2 or 1 MHz can meet your requirements. Additionally, you may find it useful to review our instrument mounting solutions under the “Moorings” category or under the “INNOVA” manufacturer.
