From the developer:
Turbulence2D is the After Effects version of TurbulenceFD. TurbulenceFD's simulation pipeline implements a voxel-based solver founded on the incompressible Navier Stokes equations. That means it uses a voxel grid to describe the volumetric clouds of smoke and fire and solves the equations that describe the motion of fluid on that grid.
