Roughness, inertia, and diffusion effects on anomalous transport in rough channel flows
Seonkyoo Yoon, Peter K. Kang
Abstract
Fluid flow and mass transport in rough channels are ubiquitous phenomena occurring in numerous engineering applications and natural processes. Comprehensive numerical simulations and stochastic upscaling elucidate how the complex interplay between channel roughness, inertia, and diffusion controls solute transport in channel flows. A mechanistic link between the complex interplay and anomalous transport in rough channel flows is successfully established.
