Abstract

Acoustic Doppler Velocimeters (ADV) are an established method of measuring three dimensional velocity components. However, when bubbles are present in the measurement area the quality of the measurement decreases rapidly. At high concentrations of bubbles, the ADV is mainly measuring the bubble velocity rather than the velocity of the water or nothing at all. Bubbles are often present for a free-discharging jet entering a body of water. This makes it difficult to measure the velocity distribution of the jet as it disperses in the water body. This paper describes a method to separate the measurements on bubbles from those on water so that the water velocity can be extracted from the ADV output files.
