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…
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…
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…
Internal stresses in low-Reynolds-number fractal aggregates
Matteo Polimeno, Changho Kim, François Blanchette
We present a numerical model of fractal-structured aggregates in low-Reynolds-number flows. Assuming that aggregates are made of cubic particles, we first use a boundary integral m…
