Comment on "Physical significance of artificial numerical noise in direct numerical simulation of turbulence"
Ryan M. McMullen, Michael A. Gallis, Ishan Srivastava +3
Recently, Liao and Qin [J. Fluid Mech. 1008, R2 (2025)] claimed that numerical noise in direct numerical simulation of turbulence using the deterministic Navier-Stokes equations is…
A Fluctuating Hydrodynamics Model for Nanoscale Surfactant-laden Interfaces
John B. Bell, Andrew Nonaka, Alejandro L. Garcia
A multispecies diffuse interface model is formulated in a fluctuating hydrodynamics framework for the purpose of simulating surfactant interfaces at the nanoscale. The model genera…
An Introduction to Computational Fluctuating Hydrodynamics
Alejandro L. Garcia, John B. Bell, Andrew Nonaka +3
These notes are an introduction to fluctuating hydrodynamics (FHD) and the formulation of numerical schemes for the resulting stochastic partial differential equations (PDEs). Fluc…
A Study of Spherical and Sessile Droplet Dynamics by Fluctuating Hydrodynamics
John B. Bell, Andrew Nonaka, Alejandro L. Garcia
We simulate the mesoscopic dynamics of droplets formed by phase separated fluids at nanometer scales where thermal fluctuations are significant. Both spherical droplets fully immer…
