Three-dimensional Vortex-induced Reaction Hotspots at Flow Intersections
Sang H. Lee, Peter K. Kang
We show the emergence of reaction hotspots induced by three-dimensional (3D) vortices with a simple reaction. We conduct microfluidics experiments to visualize…

Roughness, Inertia, and Diffusion Effects on Anomalous Transport in Rough Channels
Seonkyoo Yoon, Peter K. Kang
We study how the complex interplay between roughness, inertia, and diffusion controls the tracer transport in rough channels. We first simulate the flow and tracer transport over w…
