After an introduction to the Navier-Stokes equations and Large Eddy Simulation, we derive the ADM and discuss difficulties in constructing efficient, stable, and accurate numerical schemes for it which use finite elements for the spatial discretization. We then show how a small change to the model can resolve this critical numerical issue, and provide several numerical experiments that demonstrate the effectiveness of the modified model/scheme. |
