Broadband molecular dynamics simulation of fluid inertial effects in confined Brownian motion
Quentin Thomas, Clara Mefo Sop, Maxime Lavaud +3
Hydrodynamic memory governs Brownian motion over a broad range of timescales, from acoustic wave propagation at short times to diffusive relaxation at long times. While confinement…

The hydrodynamic response of Brownian particles in liquids is fundamentally altered by inertial forces arising from unsteady momentum transport in the surrounding fluid. These forc…
Taylor dispersion in a soft tube
Aditya Jha, Masoodah Gunny, Joshua D Mcgraw +2
Diffusion of a solute along a tube is enhanced by hydrodynamic flow, a phenomenon known as Taylor dispersion. In microfluidic applications, the compliance of the tube boundaries mo…
