Giant Nonequilibrium Fluctuations at a Reactive Surface
Hyun Tae Jung, Hyungjun Kim, Alejandro L. Garcia +4
We investigate whether giant fluctuations in a gas can induce corresponding fluctuations on a reactive surface in contact with the gas. Numerical simulations of a minimal heterogen…
Thermodynamically Consistent Incorporation of the Langmuir Adsorption Model into Compressible Fluctuating Hydrodynamics
Hyun Tae Jung, Hyungjun Kim, Alejandro L. Garcia +4
For a gas-solid interfacial system where chemical species undergo reversible adsorption, we develop a mesoscopic stochastic modeling method that simulates both gas-phase hydrodynam…
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…
