At the Multiscale Heat and Fluid Flow Lab (MFL), we have conducted a range of single-phase flow studies using Magnetic Resonance Velocimetry (MRV), including velocity field analysis and flow noise reduction based on turbulent kinetic energy.
However, because MRI detects signals from hydrogen nuclei, multiphase flows involving air have rarely been explored using MRV.
To address this limitation, MFL is conducting research that leverages MR signals from air bubbles—previously considered noise—for multiphase flow analysis.
In particular, we visualize the multiphase flow around a filter inside a dishwasher—an everyday example of multiphase flow—and analyze the flow characteristics to propose strategies for improving the filtration performance of the built-in filter.
This research is being carried out in collaboration with LG Electronics.
