Issues

Computer simulations indicate that simple liquids can display a surprising range of exotic nonequilibrium phenomena, more commonly seen in systems of macromolecules.

Theory and experiment are beginning to tell us why the motion of liquids containing very large molecules is often just the opposite of what we would expect from our experience with normal fluids.

Even the very simplest model fluid exhibits such characteristics of macroscopic nonequilibrium flow as irreversibility, shear thinning and dilatancy.

Efforts to extend ordinary linear hydrodynamics to the microscopic scale have succeeded in predicting, under certain conditions, corrections to Stokes Law and the form of the neutron scattering function.

Correlations in the positions and velocities of the particles in a dense fluid make it difficult to model their hydrodynamic behavior in the way that the Boltzmann equation models the behavior of dilute gases.
