Dynamic behaviors of the turbulent cavitating flows based on the Eulerian and Lagrangian viewpoints

The current study shows that the LCS approach together with the Eulerian method can help us to have better understandings of the cavitating flow. The Lagrangian analysis especially indicates the underlying flow physics about the mixing process and bubble growth and decline behaviors. Most of the previous related studies only focus on the flow above the upper surface. The LCSs shown in this study also emphasize the importance of the flow structure of the lower surface, which provides more insightful information for the flow control and is worth further investigation.
