Cavitation Inception in Spool Valves [PDF]
Journal of Fluids Engineering, 1981 Cavitation has been investigated in directional control valves in order to identify damage mechanisms characteristic of components of aircraft hydraulic systems. Tests have been conducted in a representative metal spool valve and in a model three times larger.

Numerical investigation of the effect of different parameters on emitted shockwave from bubble collapse in a nozzle [PDF]
Journal of Particle Science and Technology, 2021 Cavitation can be extremely beneficial for the first spray breakup and to enhance atomization quality. An Eulerian/Lagrangian approach using Reynolds average Navier-Stokes (RANS) and bubble dynamic equations was used for the prediction of cavitation ...
