Particle-laden flow
In Summer 2023, I worked as an undergraduate researcher in the particle-laden flow group of the UCLA Computational and Applied Math (CAM) REU, with principal investigator Dr. Andrea Bertozzi. We performed experiments where mixtures of viscous silicone oil and glass/ceramic beads flow down an incline. We discovered the dramatic phenomenon of jamming transition happening at high particle volume fractions, as illustrated by the video on the right.
Dramatic.mp4We participated in the Annual Meeting of the APS Division of Fluid Dynamics (DFD) in Fall 2023, presenting two posters titled "Modeling polydisperse particle-laden flow down an incline" and "Phase transitions in highly concentrated particle-liquid thin films," whose abstracts can be found here and here.
Our latest paper "A comparative study of dynamic models for gravity-driven particle-laden flows," which theoretically and numerically compares the diffusive flux and suspension balance models for predicting the dynamics of particle-laden flows, has been published at Applied Mathematics Letters, 2025. You can view it here.
In Summer 2025, I returned to the CAM REU, this time working as a graduate mentor for three undergraduate students. Together, we performed experiments and investigated theory.
For the former, we presented a poster "Transient dynamics of bidisperse suspensions on an incline" at the APS DFD of Fall 2025, whose abstract can be found here. You can also view a related Gallery of Fluid Motion video on the right.
For the latter, I gave a talk "Transient dynamics of bidisperse neutrally buoyant thin-film flow" at the DFD, with abstract here. A manuscript about this topic is also in preparation.
