Understanding the dynamics of the re-entrant jet phenomenon is of great interest for particular applications where it may occur. In spite this, the dynamics of large-scale bubble collapse are not well understood. Engineering ans Scientific Innovations (ESI) is proposing using the same methods used to quantitatively measure a hydrodynamic ram event to measure a re-entrant jet created during an uncorking event.

Benefit:
The development of the measurement suite will be beneficial in studying cavitation the associated re-entrant jet phenomenon. The measurement suite will be be used in situ to quantitatively measure the and reduce the damage caused by cavitation in a wide array of commercial applications.

Keywords:
cavitation, cavitation, re-entrant jet, Computational Fluid Dynamics, CFD, Measurement Suite, multi-phase, experimental fluid dynamics, flow visualization

Understanding the dynamics of the re-entrant jet phenomenon is of great interest for the particular applications where it may occur. In spite of this, the dynamics of large-scale bubble collarless are not understood. Engineering & Scientific Innovations (ESI) is proposing the use of the same methods applied to quantitatively evaluate a hydrodynamic ram event to the re-entrant jet problem.

Benefit:
The development of the measurement suite will be beneficial in studying cavitation associated with re-entrant jet phenomena. The measurement suite will be used in situ to quantitatively measure the cavitation bubble and reduce the damage caused by this phenomena to a wide range of commercial applications.
