Momentum fluctuations in coarse grained systems
M. Reza Parsa, Changho Kim, Alexander J. Wagner
At first glance the definition of mass and momentum appears to be uniquely defined. We show here, however, that this certainty can be misleading for many coarse grained systems. We…
Density-Dependent Finite System-Size Effects in Equilibrium Molecular Dynamics Estimation of Shear Viscosity: Hydrodynamic and Configurational Study
Kang-Sahn Kim, Changho Kim, George Em Karniadakis +2
We study the intrinsic nature of the finite system-size effect in estimating shear viscosity of dilute and dense fluids within the framework of the Green-Kubo approach. From extens…
Fluctuating hydrodynamics of electrolytes at electroneutral scales
Aleksandar Donev, Andrew J. Nonaka, Changho Kim +2
At mesoscopic scales electrolyte solutions are modeled by the fluctuating generalized Poisson-Nernst-Planck (PNP) equations [J.-P. Péraud et al., Phys. Rev. F, 1(7):074103, 2016].…
Nature of Intrinsic Uncertainties in Equilibrium Molecular Dynamics Estimation of Shear Viscosity for Simple and Complex Fluids
Kang-Sahn Kim, Myung Hoon Han, Changho Kim +3
We study two types of intrinsic uncertainties, statistical errors and system size effects, in estimating shear viscosity via equilibrium molecular dynamics simulations and compare…
Fluctuating Hydrodynamics of Reactive Liquid Mixtures
Changho Kim, Andy Nonaka, John B. Bell +2
Fluctuating hydrodynamics (FHD) provides a framework for modeling microscopic fluctuations in a manner consistent with statistical mechanics and nonequilibrium thermodynamics. This…
Molecular Hydrodynamics: Vortex Formation and Sound Wave Propagation
Kyeong Hwan Han, Changho Kim, Peter Talkner +2
In the present study, quantitative feasibility tests of the hydrodynamic description of a two-dimensional fluid at the molecular level are performed, both with respect to length an…
