Advancing Multiphase Flow Analysis with AI-Driven Optical Flow Techniques

This project pioneers the use of the RAFT machine learning algorithm for Optical Flow to analyze cloud cavitation, a damaging multiphase flow phenomenon, by quantifying its velocity field uncertainty with CFD-generated synthetic images to improve understanding and mitigation of cavitation erosion.

Study of Shedding Mechanisms in Cloud Cavitation and the scale effects on dynamics

Identified the role of Kelvin-Helmholtz instability during the shedding of cavitation clouds. Proposed a new non-dimensional number that can explain the nature of shedding observed at different scales.
