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…
Capturing non-Markovian dynamics in non-equilibrium stochastic systems using flow matching
Bhargav Sriram Siddani, John B. Bell, Alejandro L. Garcia +1
Hydrodynamic models of stochastic particle systems represented by coarse-grained stochastic partial differential equations (SPDE), such as the regularized Dean-Kawasaki (DK) equati…
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…
Molecular Fluctuations Inhibit Intermittency in Compressible Turbulence
Ishan Srivastava, Andrew J. Nonaka, Weiqun Zhang +2
In the standard picture of fully-developed turbulence, highly intermittent hydrodynamic fields are nonlinearly coupled across scales, where local energy cascades from large scales…
Thermodynamic consistency and fluctuations in mesoscopic stochastic simulations of reactive gas mixtures
Matteo Polimeno, Changho Kim, François Blanchette +4
It is essential that mesoscopic simulations of reactive systems reproduce the correct statistical distributions at thermodynamic equilibrium. By considering a compressible fluctuat…
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…
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…
Modeling Electrokinetic Flows with the Discrete Ion Stochastic Continuum Overdamped Solvent Algorithm
Daniel R. Ladiges, Jailun G. Wang, Ishan Srivastava +5
In this article we develop an algorithm for the efficient simulation of electrolytes in the presence of physical boundaries. In previous work the Discrete Ion Stochastic Continuum…
A Discrete Ion Stochastic Continuum Overdamped Solvent Algorithm for Modeling Electrolytes
Daniel R. Ladiges, Sean P. Carney, Andrew Nonaka +6
In this paper we develop a methodology for the mesoscale simulation of strong electrolytes. The methodology is an extension of the Fluctuating Immersed Boundary (FIB) approach that…
