Wasserstein-penalized Entropy closure: A use case for stochastic particle methods
Mohsen Sadr, Nicolas G. Hadjiconstantinou, M. Hossein Gorji
We introduce a framework for generating samples of a distribution given a finite number of its moments, targeted to particle-based solutions of kinetic equations and rarefied gas f…
Solving Lubrication Problems at the Nanometer Scale
Nisha Chandramoorthy, Nicolas G. Hadjiconstantinou
Lubrication problems at lengthscales for which the traditional Navier-Stokes description fails can be solved using a modified Reynolds lubrication equation that is based on the fol…
An alternative approach to efficient simulation of micro/nanoscale phonon transport
Jean-Philippe Peraud, Nicolas Hadjiconstantinou
Starting from the recently proposed energy-based deviational formulation for solving the Boltzmann equation [J.-P. Peraud and N. G. Hadjiconstantinou, Phys. Rev. B 84, 2011], which…
Efficient simulation of multidimensional phonon transport using energy-based variance-reduced Monte Carlo formulations
Jean-Philippe Peraud, Nicolas Hadjiconstantinou
We present a new Monte Carlo method for obtaining solutions of the Boltzmann equation for describing phonon transport in micro and nanoscale devices. The proposed method can resolv…
Hybrid atomistic-continuum methods for multiscale hydrodynamics
Hettithanthrige S. Wijesinghe, Nicolas G. Hadjiconstantinou
We discuss hybrid atomistic-continuum methods for multiscale hydrodynamic applications. Both dense fluid and dilute gas formulations are considered. The choice of coupling method a…
