Flow Field Mapping Using an ADV

This SonTek/YSI Acoustic Doppler Velocimeter (ADV) is being used in a laboratory to map the flow field around a dredge head. The ADV measures velocities at up to 25 Hz in a sampling volume smaller than 0.25 cubic centimeters, so intricate flow fields can be mapped by physically moving the probe. The dye was injected during the experiment as a visual indicator of the flow field.
