An intercomparison study using 3-dimensional electromagnet turbulent velocity probes, a hot-film anemometer, and an airfoil probe

An intercomparison study was performed with four Russian-made, electromagnetic probes capable of measuring three components of oceanic turbulent velocities and two 1-axis velocity sensors familiar to western scientists, namely a hot-film anemometer and an airfoil shear probe. The intercomparison measurements were conducted in a water flume tank in the MARINPO facility in Kaliningrad, Russia. Measurements were obtained in the turbulent region generated behind a grid at 3 different mean flow speeds. In all the intercomparison runs, data from the EM probes behave in a manner expected from the sensor and filtering characteristics. For all runs, data from the electromagnetic probes compare well to data from both the hot-film and airfoil probes.
