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…
Recent Modeling Advances in Dense Suspension Rheology
Orhun Ayar, Bhargav Sriram Siddani, Ishan Srivastava +1
Dense suspensions of particles dispersed in liquids are central to industrial and geophysical processes and serve as model systems for out-of-equilibrium soft matter. At high parti…
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…
An adaptive, data-driven multiscale approach for dense granular flows
B. Siddani, Weiqun Zhang, Andrew Nonaka +2
The accuracy of coarse-grained continuum models of dense granular flows is limited by the lack of high-fidelity closure models for granular rheology. One approach to addressing thi…
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…
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…
