General dynamical density functional theory for classical fluids

Phys Rev Lett. 2012 Sep 21;109(12):120603. doi: 10.1103/PhysRevLett.109.120603. Epub 2012 Sep 18.


We study the dynamics of a colloidal fluid including inertia and hydrodynamic interactions, two effects which strongly influence the nonequilibrium properties of the system. We derive a general dynamical density functional theory which shows very good agreement with full Langevin dynamics. In suitable limits, we recover existing dynamical density functional theories and a Navier-Stokes-like equation with additional nonlocal terms.
