Kinetic and hydrodynamic regimes in multi-particle-collision dynamics of a one-dimensional fluid with thermal walls

no code implementations • 12 Jan 2021 • Stefano Lepri, Guido Ciraolo, Pierfrancesco Di Cintio, Jamie Gunn, Roberto Livi

We study the non-equilibrium steady-states of a one-dimensional ($1D1V$) fluid in a finite space region of length $L$.
