Resum
The use of air bubbles for the analysis of the turbulence in the suction chamber of a gear pump with Time Resolved Particle Image Velocimetry (TRPIV) is considered. It is the first time, as far as the authors know, that the flow inside a gear pump is observed with a non-intrusive technique. Although there are drawbacks of using air bubbles as flow tracers, it is the only option available in this case, since solid particles and water drops could drastically damage the steel-made gears. It is show...
