Abstract
Cavitation takes place in a fluid flow passing through a constriction, such as a reduced bore in a pipe, to release dissolved gases. The gases can be collected and the fluid can flow along a diffuser section to recover pressure. The constriction can be formed by the axial outlet part of a votex valve included in the flow line. Cavitation in the fluid can be regulated by the control fluid supplied to the vortex valve.
