Abstract:
We have focused upon the development and validation of finite element methods for LES of turbulent flows in settings in which interaction with (possibly geometrically complex) boundaries are important. New results are presented in Section 2 on closure and convolution on bounded domains. Similarly, new near wall models were required; our method for developing these is described and one from our work is presented in Section 3. The difficulties in closure and wall modelling suggest a second approach: direct simulation of large eddy motion. We give an extension of this approach to nonlinear, equilibrium flows - a step closer to turbulence for an approach not requiring wall models or closure models.
