Query: A Modified Smagorinsky Subgrid Scale Model for the Large Eddy Simulation
  of Turbulent Flow   In the field of Large Eddy Simulation, the Smagorinsky subgrid scale model
(in some form) is the most commonly accepted and used subgrid scale model. The
purpose of this paper is to address the main weakness of the Smagorinsky model,
its poor performance near the wall. The goal is to establish a model that
corrects the Smagorinsky model near the walls while at the same time minimizing
the computational overhead. A version the Dynamic Subgrid Scale model is also
incorporated into the finite element code to facilitate comparisons with the
new model near the walls.
  One of the unique characteristics of Large Eddy Simulations as compared to
other methods of dealing with turbulent flows is the idea of filtering. In this
paper we define what a filter is and also address an issue related to filters;
the error that results when the filtering and differential operations are
interchanged. This error is studied under the context of the Finite Element
Method which allows us to focus on the function being filtered rather than the
filter kernal function, which has been the usual approach in studying this
error.
