NVIDIA PhysX PowerPack DOWNLOAD
Ecco fatto amici, NVIDIA has released the PhysX PowerPack. What is the PhysX PowerPack? Simply a new ForceWare driver version 177.83 followed by 8 PhysX demos.
The pack is available here: PhysX PowerPack @ NVIDIA – 2781Mb.
Here are two demos from this pack:
NVIDIA PhysX technology Fluid Demo
The primary purpose of the NVIDIA PhysX technology Fluid Demo is to illustrate Smooth Particle Hydrodynamics (SPH). The demo contains two different scenes, the Outdoor and the Logo Scene.
I must say the log scene part is rather impressive: the fluid simulation is really and if you switch the fluid rendering from textured quads (I think it’s that) to polygonal spheres, you can see fluid equations in action!

Wavelet Turbulence for Fluid Simulation
Appearing in SIGGRAPH 2008.
We present a novel wavelet method for the simulation of fluids at high spatial resolution. The algorithm enables large- and small-scale detail to be edited separately, allowing high-resolution detail to be added as a post-processing step. Instead of solving the Navier-Stokes equations over a highly refined mesh, we use the wavelet decomposition of a low-resolution simulation to determine the location and energy characteristics of missing high-frequency components. We then synthesize these missing components using a novel incompressible turbulence function, and provide a method to maintain the temporal coherence of the resulting structures. There is no linear system to solve, so the method parallelizes trivially and requires only a few auxiliary arrays. The method guarantees that the new frequencies will not interfere with existing frequencies, allowing animators to set up a low resolution simulation quickly and later add details without changing the overall fluid motion.
