Constraints on Turbulence Simulations
, 2008
"... The connection between anomalous scaling of structure functions (intermittency) and numerical methods for turbulence simulations is discussed. It is shown that the computational work for direct numerical simulations (DNS) of fully developed turbulence scales as Re 4, and not as Re 3 expected from Ko ..."

Discontinuous Galerkin methods for turbulence simulation
 In Proceedings of the 2002 Center for Turbulence Research Summer Program
, 2002
"... this paper we formulate, implement, and apply a discontinuous Galerkin (DG) method for the simulation of compressible turbulent flows. Discontinuous Galerkin can be thought of as a hybrid of finitevolume and finiteelement methods that has a number of potential advantages including: highorder accu ..."
