Research results summarizing the past two years efforts are presented. These include analysis of both the large- and small-scale equations of additive turbulent decomposition ATD for the 2-D incompressible Navier- Stokes equations. Both of these solution procedures are complete for Cartesian coordinates and check out is essentially finished for generalized coordinates. We discuss our method used to filter solutions to the large-scale equations, and the domain decomposition methods we are employing to recouple local small-scale solutions to produce global solutions on the small scale. We also present results obtained from our large-scale equationschaotic map turbulence modeling approach for intermittent flow.
