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 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.

We participated in the Annual Meeting of the APS Division of Fluid Dynamics 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.
