### MOVIES

Here are some selected animations from my presentations. I often use two dimensions to make it easier to visualize. Newer animations are in the QuickTime format (extension mov). To play MNG animations (file extension mng), I use mngplay under Linux and IrfanView for Windows.

- Development
of giant fluctuations (GIF)
during diffusive mixing in two dimensions without
bare diffusion (reversible, top) and with bare
diffusion (irreversible, bottom).

- "Diffusive" evolution of a line of tracers simulated
using fluctuating
hydrodynamics (animated GIF)
without bare-diffusion, and hard-disk
molecular dynamics (GIF).

- Giant fluctuations observed using the Inertial
Incompressible Coupling method (left) and a
stochastic advection-diffusion approach (right). A
fluctuation-aware version of the immersed boundary code IBAMR was
used to produce these animations.

- Giant fluctuations during diffusive mixing
of two hard-disk fluids, simulated with event-driven molecular
dynamics (left) and also with low Mach number
fluctuating hydrodynamics. In three dimensions fluctuating
hydrodynamics predicts much smaller but still giant
fluctuations, as illustrated by the mixing
of two hard-sphere fluids.

- Giant
fluctuations during diffusive mixing of two miscible
fluids in two dimensions, with no gravity (top), weak
gravity (middle), and strong gravity (bottom). A similar
"fractal" interface is seen for a wide range
of Schmidt numbers, but there are also visible
differences and the rescaling is not perfect.

- Rayleigh-Taylor
instability (unstable mixing of two ideal gases
under gravity) driven entirely by thermal fluctuations,
that is, starting with no
initial interface perturbation, as calculated
using a fluctuating hydrodynamic compressible solver (also
as QuickTime,
Flash).

- Calculation of plug flow past a disk using our particle-continuum hybrid method, which combines a stochastic particle fluid with a fluctuating hydrodynamics continuum (also as QuickTime).
- Simulation of the Brownian motion of disk through a fluid using the particle-continuum hybrid code (also as QuickTime, Flash).
- Equilibration of an adiabatic piston toward thermal equilibrium, as simulated using the particle-continuum hybrid code (also as QuickTime, Flash).
- Brownian motion of a hard-disk polymer chain through a stationary deterministic (hard-sphere) molecular dynamics fluid (also as QuickTime, Flash).
- Brownian motion of a hard-disk polymer chain through a sheared stochastic (DSMC) fluid (also as QuickTime, Flash).
